'Rats have made free bennies, and plenty of 'em, component Numero Uno of their national electoral strategy since The New Deal, for pity's sake.
If Team Mittens, Karl Rove and/or the GOP-e "brain trust" couldn't (or didn't) know enough to factor even something as basic as that into their baseline campaign equations, at any point along the way during the previous six years: it's that bald level of abject imbecility and incompetence that's the real problem, ultimately.
The GOP-e and liberals are in league with each other in their disgust and hatred of conservatives. Romney and his team deceived themselves they had the money and the superior intellect to win more votes than the childish immature president.
It may well turn out that Romney got the votes, but he did nothing to protect them from getting canceled out by vote fraud.
