Their confidence is rooted in the fact that while Clinton has multiple paths to 270 and a wide margin of error, Trump needs almost everything to go perfectly for him Tuesday in order to run the table of almost all of the key tossup states.

“If Hillary wins Florida, she’ll be next president of the United States,” Bill Clinton said while campaigning Tuesday in the state, which is essentially tied. The same is likely true for Ohio and North Carolina. And Clinton could still make it to the White House by losing both and instead winning Pennsylvania and one other state, like New Hampshire, two places where she has lead in every single poll since July…

Clinton has what Democrats say is the most sophisticated get-out-the-vote effort in history, while Trump’s campaign is still scrambling to hire canvassers in Florida with seven days to go. Get-out-the-vote efforts are typically judged to be worth about 1-3 percentage points, which could easily tip a right race, and Democrats headed into the fall with a five-to-one paid staff advantage…

Still, that doesn’t’ mean Democrats are not perturbed. They are.

They could almost taste an easy, uplifting victory just a few days ago that would serve as severe repudiation of Trumpism and come with the kind of long coattails that could ensure Clinton’s presidency was not merely one long war with a GOP-controlled Congress.
