Further, the vote that's happened so far, on whether the trial is even Constitutional, is, at least according to any kind of common sense, a complete nonsense. Of course it's constitutional: otherwise, a President would in effect be free to commit "High Crimes and Misdemeanours" as long as the time remaining would mean that any fair Senate trial couldn't be organised in time. This could even include resignation -- which is no consequence either. A President who resigns can always try to return to office later, and is not barred from seeking the vice-Presidency or any other High Office, but the literal understanding of the Republicans' vote today (and a fortnight ago) is that resignation would be consequence enough. It is not.
Most Republicans are bowing to political pressure by trying to declare the trial itself unconstitutional. There's no sense in this argument, and I'll bet that most of them know that.
As a further aside, it's noteworthy that one Republican who voted against holding the trial two weeks ago voted *for* it today; perhaps there is hope yet that a few more will switch sides, or, at least, will listen without prejudice to the case and vote on its objective merits.
As it is, this is likely to mark the first time in US history that Senators of their own party have voted to convict the former President; even though the threshold of 67 is almost certainly impossible, that in itself would be of huge significance.
