Combover only grow stronger for that 10% of the electorate that shows up for Republican Primaries. When people are actually paying attention, his clownish antics are going to wear very think very quickly
The thing is, these same predictions were made about Ronald Reagan. The most laughable one was that he was "too old" to be elected! Note, both Hillary and Sanders would be older than Reagan when they took office. We've certainly come a long way in our thinking on this, haven't we? Other than the age thing, it was that Reagan was too much of a "loose cannon" and would start WWIII... do you really trust Reagan with his finger on the red button? All through the primaries he was a running joke... a washed up B-film actor with no experience in Washington.
It's difficult for people who were not there at the time to comprehend this. When he won the GOP nomination, all the political insiders and pundits, the GOP establishment, the mainstream media, the DNC and Carter campaign were
all predicting that Carter would beat him in a landslide. In fact, that is the primary reason Reagan selected GHWB as his running mate, to try and lock down some of the establishment party vote which his campaign thought was crucial at the time. Turns out, he didn't need any help, he won one of the most lopsided elections in history.
