Democrats for Rubio

[Fuzzy Bear]

I would think most Democrats who would vote for one of the most conservative members of the Senate are probably Republicans who forgot to update their registration's party affiliation info.

Many Democrats voted for Reagan who was very right wing for the time

Many of those Democrats were either (A) Southern White Democrats, or (B) urban, mostly Catholic inner-city white voters who registered Democratic to vote in the Democratic Primary for their city officials.
