I think another thing being overlooked is the enthusiasm factor. Obviously Hillary has none. Bernie’s is okay. Trump’s is YUUUGE! Who will actually get the most people off the couch and out to the polls? I think we know the answer already.
Then why didn't he do it Iowa? In how many other states will his enthusiasm fail to measure up to the hype?
People wanted the hope Reagan gave them. People want the liberal fascists stopped and the bashing of everything from Caucasians to Christianity to men to marriage to stop ... and a large minority of the population sees one man, Trump, as the only one to save them.
Note: I don’t think Trump would be the dictator liberals are afraid of, but they ignore Obama ignoring the courts and legislation that would make it easier for anyone after him to rule by dictate. So if anyone else does become a dictator ruling by decree, that is Obama’s legacy.
