In the blizzard of data about midterm elections, you are always looking for a single item which gives some clarity to the entire gestalt. I believe I have found it.

Since 1900, there have been 28 midterm elections. The party that controls the White House has lost seats in 26 of the 28. When it comes to the U.S. Senate, everybody now is in agreement that three seats held by the Democrats are gone (Montana, West Virginia and South Dakota). I know I projected a possible scenario where South Dakota might stay Democratic — disregard that previous article.


Republicans need to take three more now held by Democrats. The conventional picks are Arkansas, Alaska and Louisiana. These three have one thing in common: Two years ago they went big for Republican presidential nominee Mitt Romney, and the president is even more unpopular now. North Carolina is the other one that Republicans are savoring over. But the Democratic incumbent, according to the most recent polls, seems to be in the best shape there. In addition, Obama narrowly won there in 2008 and narrowly lost there in 2012.

What makes the Democrats most nervous and deeply worried is that there are three states in which the Democrats were supposed to be in good shape and safe.

New Hampshire — which reports early — is the No. 1 example. Jeanne ShaheenCynthia (Jeanne) Jeanne Shaheen2020 forecast: A House switch, a slimmer Senate for GOP — and a bigger win for Trump Lewandowski decides against Senate bid Biden would consider Republican for VP 'but I can't think of one right now' MORE is a former two-term governor and is well-known and was thought to be in no trouble. Six years ago, she beat Republican incumbent Sen. John Sununu. Her Republican opponent is a former U.S. senator — but not from New Hampshire! Scott Brown used to be a senator from neighboring Massachusetts, but he lost his seat two years ago. One would reasonably think that voters from New Hampshire might resent Brown and label him a carpetbagger and not vote for him. But he's got Shaheen running scared.

In Colorado, the incumbent Democrat is Sen. Mark UdallMark Emery UdallDemocrats will win back the Senate majority in 2020, all thanks to President Trump Poll: Trump trails three Democrats by 10 points in Colorado The Hill's Morning Report — Trump and the new Israel-'squad' controversy MORE. Very few observers thought he was in jeopardy. But his Republican opponent is Rep. Cory GardnerCory Scott GardnerMcConnell keeps press in check as impeachment trial starts Progressive group launches campaign targeting vulnerable GOP senators on impeachment What to watch for as Senate organizes impeachment on day one MORE — not Ken BuckKenneth (Ken) Robert BuckSmaller companies testify against Big Tech's 'monopoly power' The Hill's Morning Report - Sponsored by AdvaMed - House panel expected to approve impeachment articles Thursday House passes bill that would give legal status to thousands of undocumented farmworkers MORE. And that's the problem for Udall. Two years ago, Sen. Michael BennetMichael Farrand BennetWarren ad claims Trump fears her most Sanders to headline Iowa event amid impeachment trial On The Money — Presented by Wells Fargo — Sanders defends vote against USMCA | China sees weakest growth in 29 years | Warren praises IRS move on student loans MORE had the good fortune to face Buck, a Tea Party favorite who turned off moderate Republicans and independents.

Michelle Obama did not help matters when, campaigning for Udall, she called him a fifth-generation Coloradan. He moved there in his 20s. Anybody with a smattering of political knowledge would know he is the son of former Rep. Mo Udall and the nephew of former Secretary of the Interior Stewart Udall. The Udalls are the first family of Democrats in Arizona.

Iowa is another state where Democrats were not supposed to be in trouble. The incumbent Sen. Tom HarkinThomas (Tom) Richard HarkinTrump's trial a major test for McConnell, Schumer New Hampshire parochialism, not whiteness, bedevils Democrats Democrats must question possible political surveillance MORE is retiring and Bruce BraleyBruce Lowell Braley2020 caucuses pose biggest challenge yet for Iowa's top pollster OPINION | Tax reform, not Trump-McConnell feuds, will make 2018 a win for GOP Ten years later, House Dems reunite and look forward MORE is presently a House member.

Iowa has never sent a woman to Washington. They very well might, soon.

New Hampshire, Colorado and Iowa went for Obama not once, but twice. But the three Democratic candidates don't want him to set foot in the state. In previous articles, I hypothesized a creative scene where Georgia and Kansas might save the day for the Democrats, but that might be my fertile imagination. The reality is that, as one non-Democrat, President George H.W. Bush, would aptly say on the eve of the elections, the "Donkeys are in deep do-do."

Much has been made of the fact that Obama's base of single women, blacks and Latinos and young people historically don't vote in midterms. Well, these constituencies should wake up and realize that elections affect their lives and their futures: It's not okay just to vote every four years, when it's a presidential election. Every election is important. The U.S. Senate confirms Supreme Court nominees. That in itself should be enough to get these people to vote in off-years. Senate Majority Leader Harry Reid (D-Nev.) is worried enough to send out a last-minute fundraising appeal to longtime Democratic donors saying that if Republicans take over that body, they could try to impeach Obama. You might remember the House indicts, but the Senate actually convicts, and thus can remove the individual from the office.

That's how ominous it looks the day before judgment day for the Democrats. Democrats are praying to stay alive and fervently hope all those polls and pundits are wrong.
