They have the obligation to certify that he is eligible. If they didn’t . . . . . .
There unfortunately seems to be no legal obligation for parties to do this, or no legally required procedure, at any rate.

I’m pretty sure the Clintons knew. Remember Bill’s comment when asked about the possiblity of Obama running (some months before the campaign)? I don’t remember the exact words, but it was something to the effect of “yes, as long as he’s a citizen, that’s all he needs.”
