Maybe, but he's been a public figure for a long time, and I'd be surprised if there are any huge dark secrets to be revealed.
He certainly will not get support from the strict social conservatives who insist that their candidate be against abortion in all cases, but that's not even the current GOP platform position on the issue.
Others disqualify him because he's gotten a couple of divorces.
But that stuff is already out there, and he's still leading the pack at the moment if you believe all the polls. He benefits because there is nobody who is demonstrably to his right on social issues who has a prayer of winning the nomination.
Seems to me it is a bit too early to be making that claim.
