Obama would survive it because he's the unsinkable Barack.
If Mitt was caught up in a sex scandal, his campaign would be over and it would be an absolute blowout. It would be the straw that broke the camel's back. Fortunately, I think Romney has more character than that. Plus, his wife is an amazing woman who he has no reason to cheat on.
I like how you imply by that statement that Michelle Obama is not an equally nice person. Rather hypocritical, don't you think?
Tangent alert, but I'm going to take this time to say that Ann Romney is thoroughly unattractive. Whether that makes her susceptible to cheating is another issue, but I needed to express this opinion somewhere and I have now done so.
