Yes she can and likely will win.
Because the GOP does not have a candidate that can beat her. The RINO's won't get the conservative vote and the conservatives don't have anyone with star power (or for that matter name recognition).
The good news is that with a Clinton presidency and a liberal Congress this country will go down the tubes over her first term. That gives an opoortunity for a true conservative to position himself as someone ready to make the tough choices neccessary to restore the Republic.
The same was said of Clinton 42.
