How are either of these candidates the "most unelectable" in history? Obama is drawing fantastic numbers from independents and people who may not have voted for another candidate. From everything I can tell, he's 'more electable' than any Democrat in my lifetime, including Bill Clinton (who, obviously, won and remains immensely popular).
No matter how hard some try to paint him as a fringe candidate, the people don't seem to be buying it.
And Hillary - a woman with a huge amount of name recognition, tied into the above immensely popular former President, a legislative record that's difficult to attack because it was crafted to be all things to all people. I don't like her, and I think her negatives would make the race more competitive - but she's hardly less electable than Walter bleepin' Mondale or John Kerry.
The idea that Hunter and Thompson - a no-name and a sleepy grandpa - would wipe the floor with either of them requires serious ideological blinders. These guys didn't even have enough juice to win the nomination, much less run the table in the general. The country's mood is not amenable to party-line conservatives. Anti-immigrant rhetoric loses as many votes as it gains, and Thompson was basically a continuation of the Bush regime. Which is, I believe, still polling in the low-to-mid 30s.
