Bloomberg is an obvious challenger. Though he calls himself a Pub, he's clearly a liberal. His resume shames HRC’s resume. He has money to burn on a campaign. He was a successful mayor of a major liberal city, New York.
Clooney could beat HRC purely on charm & wit. Clinton lacks both. The Rats elected an incompetent, ignorant fool in 08 & 12, based on charm, wit, & race (I think the white Rats are getting tired of rap music & posses at all their parties). Why not again in 16?
Between the 2, Bloomberg has the best shot, though Clooney wouldn't surprise me.
They should run Wendy Davis. She hates a fetus as much as Hillary! does and she’s a lawyer.
