The upcoming Donald Trump impeachment trial is likely to have an effect on the race for the Democratic Presidential nomination.
Since it is likely to be held in January, a month before the Iowa Caucuses, New Hampshire Primary, South Carolina Primary, and Nevada Caucuses, the six Senators (Elizabeth Warren, Bernie Sanders, Amy Klobuchar, Cory Booker, Kamala Harris, Michael Bennet) who are candidates for President will be unable to campaign, on days of the trial.
They are required to sit in their Senate seats and listen to the testimony, without speaking, and cannot choose to do otherwise, as it would be against protocol.
If it stretches through the whole month of February, they will not be able to campaign in the 14 states scheduled to vote on Super Tuesday, including California, Texas, Virginia, Colorado, Massachusetts, Minnesota, North Carolina, and Tennessee, among others.
That should help such candidates as Joe Biden, Pete Buttigieg, Julian Castro, Steve Bullock, Tulsi Gabbard, Tom Steyer, Michael Bloomberg, and Deval Patrick.
Whether the impeachment trial will ultimately change the dynamics long term of the race will be interesting to see if it evolves.
