One thing Trump has over everyone, including Cruz, is that he supported and endorsed Obama and praised Hillary back when.
Yeah, that makes his judgment questionable but it also means he is the only one who can say, "I believed Obama, like millions of Americans, when he said 'If you like your doctor ' and that premiums would fall.. . .' Now it's clear that was a disaster."
So in the minds of some of the "independents" and even non-whacko Dems, Trump makes it ok to say "Yeah, Obama was a mistake."
Great point, LS.
Just remember one thing, Reagan was a Democrat for a very long time before he became a Republican.
Minds and hearts change, including the People that we respect the most.
