A good motto for Election Day is usually “expect the unexpected.”

That certainly held true on Tuesday night. Ultimately, the midterms turned out to be an even better than expected night for Republicans. They locked up many races relatively early and by large margins, despite polling in recent weeks that indicated most competitive races were close.

But that bigger than expected GOP wave gave way to a lot of surprising moments. Here are The Hill’s top 10: 

Some of the losses by Democrats weren’t surprising, but the margins were. Incoming Senate Majority Leader Mitch McConnellAddison (Mitch) Mitchell McConnellKey GOP senators appear cool to Kavanaugh accuser's demand Trump hints at new executive action on immigration, wants filibuster-proof Senate majority The Hill's Morning Report — Sponsored by United Against Nuclear Iran — The Hill interviews President Trump MORE (R-Ky.) won by 15 points over Kentucky Secretary of State Alison Lundergan Grimes. Rep. Tom CottonThomas (Tom) Bryant CottonSprint/T-Mobile deal must not allow China to threaten US security GOP senators condemn 'vulgar' messages directed at Collins over Kavanaugh GOP turns its fire on Google MORE (R-Ark.) toppled Sen. Mark PryorMark Lunsford PryorMedicaid rollback looms for GOP senators in 2020 Cotton pitches anti-Democrat message to SC delegation Ex-Sen. Kay Hagan joins lobby firm MORE (D-Ark.) by 17 points. And state Sen. Joni Ernst (R) defeated Rep. Bruce BraleyBruce Lowell BraleyOPINION | Tax reform, not Trump-McConnell feuds, will make 2018 a win for GOP Ten years later, House Dems reunite and look forward Trump: Ernst wanted 'more seasoning' before entertaining VP offer MORE (D-Iowa) by 8 points and effectively sealed the deal for Senate Republicans’ majority. Recent polling showed all of those candidates ahead, but by single digits.

Senate Republicans won a clear majority before midnight on election night. Signs initially suggested that Americans wouldn’t know who won the Senate on Tuesday. The open Senate race in Georgia once appeared likely to go to a runoff on Jan. 6. And if Republicans couldn’t pick up seats elsewhere, a Dec. 6 runoff in Louisiana could have resulted in a cliffhanger. Sen. Pat RobertsCharles (Pat) Patrick RobertsPat Robertson asks followers to help cast 'shield of protection' ahead of hurricane Cruz gets help from Senate GOP in face of serious challenge from O’Rourke The farm bill gives Congress a chance to act on the Pet and Women Safety (PAWS) Act MORE (R-Kan.) also appeared in danger of losing his seat to Independent Greg Orman. But Roberts and Georgia GOP Senate candidate David Perdue won decisively well before midnight on Tuesday. In late-closing Alaska, Republican Dan Sullivan is ahead of Sen. Mark BegichMark Peter BegichElection Countdown: Trump plans ambitious travel schedule for midterms | Republicans blast strategy for keeping House | Poll shows Menendez race tightening | Cook Report shifts Duncan Hunter's seat after indictment The Hill's Morning Report — Trump’s legal jeopardy mounts after Manafort, Cohen felony counts Dunleavy, Begich win party nods in 3-way race for Alaska governor MORE (D), though the race is too close to call.

Sen. Mark WarnerMark Robert WarnerRussia docs order sets Trump on collision with intel community Hillicon Valley: North Korean IT firm hit with sanctions | Zuckerberg says Facebook better prepared for midterms | Big win for privacy advocates in Europe | Bezos launches B fund to help children, homeless Bipartisan trio asks US intelligence to investigate ‘deepfakes’ MORE (D-Va.) is barely hanging on. Polling showed Warner ahead of GOP candidate Ed Gillespie by double digits earlier this cycle and still by an average of more than 5 points in recent weeks. Democrats generally weren’t as worried about Warner as they were about incumbents in North Carolina and New Hampshire. Now, Warner currently leads Gillespie by just less than a percentage point with all precincts counted. The race appears headed to a recount, and it could take days, if not weeks, for a final call.

Rep. John BarrowJohn Jenkins BarrowOur democracy can’t afford to cut legal aid services from the budget Dem files Ethics complaint on Benghazi panel Barrow thanks staff in farewell speech MORE (D-Ga.) lost. Barrow, the last white House Democrat from the Deep South, was the perpetual survivor. Despite being a perennial GOP target in a conservative district, Barrow managed to win reelection by maintaining a centrist voting record and a folksy appeal. His luck ran out Tuesday as the Democrat lost by 9 points to GOP businessman Rick Allen, one of the most formidable opponents he’d faced in the redrawn district. 

Sen. Kay HaganKay Ruthven Hagan2020 Dems compete for top campaign operatives Senate GOP rejects Trump’s call to go big on gun legislation Politics is purple in North Carolina MORE (D-N.C.) lost. Both sides always knew this race would be close, but the networks called the race for North Carolina state Speaker Thom Tillis (R) just a few hours after the polls closed. At a minimum, many Democrats predicted Hagan and Sen. Jeanne ShaheenCynthia (Jeanne) Jeanne ShaheenSome employees' personal data revealed in State Department email breach: report Dems seek ways to block Trump support for Saudi-led coalition in Yemen Hillicon Valley: Trump signs off on sanctions for election meddlers | Russian hacker pleads guilty over botnet | Reddit bans QAnon forum | FCC delays review of T-Mobile, Sprint merger | EU approves controversial copyright law MORE (D-N.H.) would win reelection and stave off Senate GOP gains. Only one of those ended up being true. 

Rep. Dan Maffei (D-N.Y.) lost, and by a huge margin. Maffei was a top GOP target throughout the 2014 election cycle, and political handicappers eventually rated the race as a toss-up. Still, no one expected Maffei would lose to Republican John Katko by 19 points. After all, former Republican Rep. Ann Marie Buerkle defeated Maffei by less than a point in 2010 after weeks of counting votes. Maffei won the seat back in 2012, but it’s hard at this point to see him running for the seat again after losing so decisively.

Early calls in Illinois predicted a good night for the GOP. Competitive Illinois races went decisively for Republicans relatively early in the night. Former Rep. Bob Dold (R) unseated Rep. Brad Schneider (D) in their rematch, Rep. Rodney Davis (R) fended off a challenge from Democrat Ann Callis by 17 points, and state Rep. Mike Bost (R) toppled freshman Rep. Bill Enyart (D) handily by 11 points. Republican Bruce Rauner also won the governor’s race against Gov. Pat Quinn (D), which put the cherry on top for the GOP in President Obama’s home state. 

Freshman Rep. Steven Horsford (D-Nev.) lost. Horsford’s race wasn’t on either party’s radar until the final weeks of the campaign. The Democratic Congressional Campaign Committee funneled hundreds of thousands of dollars in a late attempt to save Horsford in a district that Obama won handily in 2012, after American Crossroads went on a spending blitz there. But it was too late, and Nevada state assemblyman Cresent Hardy pulled the upset Tuesday night. 

Incumbent House Democrats not expected to be in play are too close to call. Three House Democrats ended up having nail-biter election nights. As of Wednesday afternoon, The Associated Press had still not called the reelection races of Reps. John Delaney (D-Md.), Jim Costa (D-Calif.) and Louise Slaughter (D-N.Y.). Delaney and Slaughter currently hold narrow leads, but Costa is trailing Republican Johnny Tacherra. Republicans already expanded their majority to their largest since the 1940s, but these unexpected seats would give the GOP even more opportunities.

Democrats lost the Maryland gubernatorial race. Lt. Gov. Anthony Brown (D) was one of the few candidates this cycle who had Obama campaign on his behalf in the traditionally Democratic stronghold. Republicans attacked Brown for his ties to Gov. Martin O’Malley (D), particularly for the tax increases enacted under the current governor. In the end, GOP businessman Larry Hogan pulled out an upset by a 9-point margin, showing just how high the GOP tidal wave had crested.
