Do you think Romney is intelligent?
If not, read no further.
If so, which do you think an intelligent person would choose...
1) Saying he doesn't remember (which causes opponents to go bat shit crazy about you not caring) but that he is sorry if one of his pranks hurt someone.
2) Saying 'it was a prank of a high school kid, I went too far, I apologize for it.'
Which would a sleazy politician do Jarod? What could he possibly gain by saying he doesn't remember? Unless he honestly doesn't remember. There is no gain. If he remembered and was fearful of evidence coming out, he could simply have gone with number 2 above. If he remembered and thought there was no evidence, he could have denied it.
In what case would him stating 'he didn't remember' help him?
