They can only destroy him with some real facts and that could be counterproductive for Hillary in the general election. Blacks, the Dems most loyal constituency, will not turnout for Hillary and destroying Obama effectively removes him from being the VP nominee. I just don't see the Dem party committing political suicide by overturning the results at the ballot box and stealing the election for the Clintons over the black guy. Such an action would not only affect this election, but future ones.
Clintons think NOW, not Long Term.
They are both over 60, both narccicsts, and both could care less what happens to the Party, since they built a SHADOW PARTY, all thier own...
