The Carter analogy is false. That demographic of 25 years ago no longer exists, and Carter lost, according to many, on the sands of the Iranian desert when the rescue mission of American hostages went down in flames, literally. A graphic that was broadcast each night on American TV just before the election.
The Establishment was using that excuse in 1980.
As for the demographics, Trump is the only one who can reach Americans who still want to save her.
Cruz isn't going to!
Note the polls are now pushing Kasich as the one who can REALLY beat Hillary!
