She may very well be. As you said, she's unpopular with Democrats and of course there are all the scandals. Normally I'd have a hard time thinking Sanders even had a shot, but that Barry was actually elected -- twice -- demonstrates even an anti-American socialist can be elected.
So many folks, guys like Hugh Hewitt and I'd say probably most FReepers, believe that Democrat's can't win if it's not close -- in other words, that vote fraud by Democrats is too minor to make a real difference if we only get our act together. That kind of thinking is not only wrong, it is dangerous to the point of being figuratively suicidal.
The ONLY reason Democrats cheat is that much of the time, it's the ONLY way they can win.
