That puts the beginning of arguments at the end of next week. There’s only one week after that before the Iowa caucuses.

If the trial lasts only two weeks, it’ll end the week before Feb. 11, when voters in New Hampshire go to the polls to pick the Democratic candidate. But it’s very possible that the trial will last three weeks, putting it into the week of the state’s primary.

And if the Senate decides to call witnesses, it could go even longer, overshadowing the Feb. 22 Nevada caucuses, possibly even lasting right up until the Feb. 29 South Carolina primary.

For candidates who are struggling to stay afloat financially, like Klobuchar and Bennet, this could be a fatal body blow.
