It would be the sames as a Santorum supporter supporting Romney, if Santorum dropped out and Gingrich were still in the race, just over bitterness. It makes no sense. ROMNEY IS THE ENEMY OF ALL CONSERVATIVES. PERIOD.
It’s ridiculous. Honestly, though, the support for Romney as a second choice makes sense. The hatred toward Rick has done nothing but help Romney. Those who support Romney as a second choice seem to hate Rick so much because he is so socially conservative and outspoken about it, hence the nicknames like “Saint Rick” and “Sanctimonious”.
