Senator Tammy Baldwin, a Wisconsin Democrat seeking re-election, has noticed voters returning to the same question in recent days as she crisscrosses her state to make the case for her campaign: Does she think President Biden can win in November, and should he even try? “Typically, I’ll go to an event; I’ll share my remarks,” Ms. Baldwin said in an interview on Friday at a newly opened campaign office in southwestern Wisconsin. “And then people come up one by one and — at first in a whisper — are really concerned.”A soft-spoken two-term senator who has carved out a reputation for her cross-party appeal, Ms. Baldwin easily cruised to victory in 2018, and her race this year was never expected to be ultracompetitive, even in this crucial swing state. But rising concerns about Mr. Biden’s age and fitness to run have introduced new risks for Democratic candidates like Ms. Baldwin just 100 days out from Election Day, imperiling even seats that were once considered relatively safe for the party. That has left Democrats already anxious about losing the White House to former President Donald J. Trump contemplating the prospect of widespread losses in Congress that could leave the party locked out of power altogether during a Trump presidency and well beyond.
