Republicans have clinched Senate control in an election night that saw Democrats around the country crushed by the growing unpopularity of President Obama.
Democratic losses piled up throughout the night, with the GOP securing a Senate majority before midnight as Sen. Kay HaganKay HaganClinton's lead in NC elevates Senate race Democratic National Convention event calendar 10 Senate seats most likely to flip in 2016 MORE lost in North Carolina and Republican Joni Ernst won an open seat in Iowa.
Incumbent Democrats also fell in House and gubernatorial races, adding to the scale of the party's defeat. High-profile Democratic targets including Wisconsin Gov. Scott Walker (R) prevailed, and the party failed to pick up a single Senate seat.
Republicans won open seats held by Democrats in Montana, West Virginia, Iowa and South Dakota, and knocked off incumbents in North Carolina, Arkansas and Colorado.

McConnell was declared the victor in his closely watched race as soon as polls closed in the Bluegrass State, defeating Democrat Alison Lundergan Grimes to earn a sixth term. Democrats had early hopes for the Kentucky secretary of State's candidacy, but her campaign couldn't take advantage of the senator's unpopularity in the state.
McConnell had to wait for several more hours to learn which way Senate control would fall. But the GOP leader's counterpart admitted just before midnight that Democrats had been ushered from power.
"I'd like to congratulate Senator McConnell, who will be the new Senate Majority Leader. The message from voters is clear: they want us to work together. I look forward to working with Senator McConnell to get things done for the middle class," said now-Senate Majority Leader Harry ReidHarry ReidDems' Florida Senate primary nears its bitter end Trump haunts McCain's reelection fight 10 most expensive House races MORE (D-Nev.).
The change in power means that Obama will spend the last two years of his presidency dealing with an emboldened all-Republican Congress that intends to challenge him on major legislation and, in the words of McConnell, take the country in a “new direction.”
Hagan's loss to state Speaker Thom Tillis was one of the most surprising results of the night, and her fall sealed the Democratic Party's 2014 fate.

Rep. Steve Daines (R) then won the open Democratic-held seat in Montana.
Republican leaders crowed over the victory, arguing voters had sent a strong signal about which party they want in control in Washington.
"The American people have put their trust in the Republican Party, sending a GOP majority to the U.S. Senate. I want to congratulate all our candidates tonight," Republican National Committee Chairman Reince Priebus said in a statement. "Our party's principles and message resonated with voters across the country. This was a rejection of President Obama's failed polices and Harry Reid's dysfunctional Senate."
