I'd rather vote for a 'flip-flopper' than an 'etch-a-sketcher' any day of the week
Some people are calling Obama a 'flip-flopper' because of his recent change about marriage equality. Opinions change and evolve over time - nothing wrong with that. I know there are plenty of times when I thought one way but as I learned more details I realized that perhaps my original opinion was wrong.
Romney; however, thinks the public is too stupid to track down his former opinions on a variety of topics. Although Republican, Mitt always came across as someone a bit less hardcore than others but after the 2010 mid-terms he knew that to win a primary he would have to disavow previous 'non-hardcore-right' thoughts. But instead of saying 'my opinions have evolved, Mitt is just hoping you won't find those clips of him stating his old opinions. He really thinks he can 'erase the etch-a-sketch' and no one will be the wiser. I guess Mitt neverheard of YouTube and the fact that every smartphone has a video camera in it.
