First it would have to be determined that 0bama is indeed Constitutionally-ineligible, then it would have to be determined that Biden had full knowledge of same and said nothing. Do you honestly believe that he would have been the only Dem to have that knowledge? Do you see Biden keeping his big trap completely closed while proceedings discrediting him are taking place, he doesn't name the other Dems who also knew full well and didn't say, names like Pelosi, Clinton, Reid, etal??
I don't see it happening ... if it is actually looked into, determined that 0bama is a fraud, the best we can look forward to is a crippled Biden administration until 2012, where he will not run for re-election. I would have to believe that he and the Dems would be a bit more careful about pushing the junk that Americans don't want as well, the bruise, injury to them, their party, their standing may not even be sustainable at that point.
