If Hillary Clinton is the nominee, she will be tough to beat no matter who is the nominee..she could come out and say she ordered the hit on Ambassador Stevens and she would still get the votes
One reason Hilary is hard to beat is that republicans starting in 2008, including Sarah Palin, went all out praising her in the foolish belief it would appeal to liberal women voters.
But then republicans have made careers out of praising democrats, while the dems call them nazi murdering racists. And I am not exaggerating they call republicans exactly that all the time.
