When Romney ran for President many people didn't like him but rallied around him rather than support 4 more years of Barry. Voters held their noses and voted for Romney. Now Romney is showing his ass rather than showing the same unity people gave him. At a certain point, as the Establishment always demanded of GOP voters, you hold your nose and vote for the GOP candidate.
Ryan was Romney's VP - I get it. Guess what, Ryan....it's still YOUR and the GOP ESTABLISHMENT'S turn to take your own advice: Hold your nose and vote for / support the people's choice, Trump.
