I would vote for a Democrat over a Republican I deem unacceptable. That’s because the bad apple Republicans will infect the Party, and we need the Party to stand something so that we even have a shot in the long run to stop the destruction of what we believe in.
That’s why I would vote for the Democrat in Mississippi because the strategies that were employed against the Tea Party in the Primary are more dangerous to let stand than a single Senator.
I voted for Mark Green over Bloomberg for NY mayor in 2001. Bloomberg was the nominal Republican at the time, but I couldn’t stand him from the get-go.
