Mitt Romney said some funny (and disparaging) things about Donald Trump today. John McCain concurred with those funny things. So the Republican nominees from 2008 and 2012, losers both, think that Trump is unworthy of the 2016 nomination.
McCain was the sober thinker that gave us Sarah Palin, his running mate (Palin is supporting Trump this go 'round). Romney was the principled Conservative that almost tapped Chris Christie as his running mate (Christie now supports Trump too). Oh yeah, Romney also joyfully accepted Trump's endorsement in '12.
Both Romney and McCain seem to be overlooking two important facts. First, the Republican electorate, such as they are, prefer Trump to the other clowns offered up by their party this year. Second, don't they realize that they were just the latest in a long line of radical Conservative robots that laid the groundwork for the rise of Trump?
When the overriding theme is "Government is your enemy, and can't be trusted!", it's only a matter of time before a Trump will rise from the muck and mire to perfectly embody this Republican dogma of the last thirty-five years.
Chickens have that natural tendency to come home to roost.
