During the trial, the Senate is expected to be in for six days a week rather than its usual four; logistics alone will throw the early-state advantage to Biden, Buttigieg, Andrew Yang and Tom Steyer.

However, the trial’s focus on Biden could be awkward. Trump was impeached in December over charges he abused his power by pushing Ukraine to investigate the former vice president and his son. Trump and some GOP allies are still demanding to subpoena both Joe and Hunter Biden, who served on the board of a Ukrainian energy company.

But Biden and the rest of the field outside the Senate can at a minimum stay in Iowa and New Hampshire without worrying about an uncertain Senate schedule.

“It depends, in part, on how well Joe performs while all of my colleagues are stuck here for the impeachment trial. If he tears it up and knocks the ball out of the park all over the early primary states, then it’s a plus,” said Sen. Tom Carper (D-Del.), a Biden supporter. “There’s going to be more attention on him. … And it should be an overall positive.”
