“what about the fact that 20-30% of Democrats are crossing over and voting for Trump now?”
These are what were once called the “Reagan Democrats”.
They are Democrats who were sick of the politically correct, lying liberals who run the Democrat Party.
The Reagan Democrats were why Reagan won such huge landslides even though the GOP establishment did not like him.
You sure about that? That these Reagan Democrats crossed over and chose McCain and Romney too then? I just don’t see that being the truth, somehow. It is much more likely that the leftists figured that they could skew the election by picking a GOP candidate that was most likely to lose. And they were correct in that assumption.
