The text in the Gallup article about this chart says it is a tie between Republicans and Democrats (range of error). Democrats need to win and beat Trumpism. That's going to require building a strong base. We can't ignore the current weaknesses in the Democratic Party.

I’m a former independent who registered as a Dem to be able to vote in my primary. I’ve stayed, but don’t agree with everything. And I’ve had red lines in the past. That’s a luxury we can’t afford. I think/hope dems will kvetch but vote in 26 so we have a democracy in 28.
