We don't talk about this enough because we are so focused in the mounting evidence against Donald Trump and the occasional minor rift in the Republican party, but for expectation-setting purposes, it's probably wise to remind everyone that the odds of Trump being convicted by the Senate are still very very slim. It requires 67 votes in the Senate to impeach the President. There are 46 Democrats and two Independents who caucus with the Democrats. Assuming every Democrat votes for impeachment, we still need 19 Republicans to sign on. We might get Romney. We might get some swing-state Senators like Susan Collins or Cory Gardner. Lisa Murkowski is independent enough in Alaska that she might sign on. There are probably a handful of Republican Senators who are not running for reelection or are retiring, like Richard Burr, who might be convinced to vote to impeach.

But all of those scenarios are unlikely, and even in the Senate, Republicans might continue their "process" argument, which is to say: They can ignore the evidence and vote against impeachment because, they will argue, they didn't agree with the way the House conducted the investigation. It's a long shot, and given the fact that a vote on impeachment probably will not happen until next year, some Senators may simply argue that the American people should be left to decide at the ballot box. Never underestimate the Republicans' ability to turn the debate about one thing into a debate about something completely different.

That's not to say that things couldn't break the Democrats' way. Public hearings could provide explosive testimony. More damning evidence may be revealed. Trump could completely meltdown. I'm willing to bet, however, that all three of those things will happen, and the President still will not be impeached. The Republicans, after all, are making no effort whatsoever to make a Plan B, should Trump be impeached.

The Senate will almost certainly find a reason not to impeach the President, and that reason almost certainly will have nothing to do with the facts.

But impeachment is what we wanted. It is what is necessary. It will be incumbent upon Democrats, and on Democratic voters to ensure that doing the right thing does not blow back on us. If Trump is not impeached, it's because the Republicans believe that their President is above the law. It's because they are cowards. It's because they're more interested in their own re-election prospects than upholding the Constitution. It's because they are afraid of Donald Trump. It will be the responsibility of the Democrats to forcefully make that argument every single day. This is not -- as the Republicans will argue (and already have) -- about nullifying the (illegitimate) results of the 2016 election. It's about holding the President accountable for interfering in our elections, for corruption, for abusing his office, and for governing by conspiracy theory. Whether Trump is impeached or not, we cannot survive another four years of that.
