Maybe, let's discuss in detail.
These polls are lame.

Let's discuss details.
What I know of him is that he was Speaker of the House - I think the only U.S. President to have been so. After being Speaker, he was elected to one 2-year term as Governor, but lost re-election, then lost a rematch another 2 years later.
In 1844, he wasn't even seeking the Presidency. He was seeking the Vice Presidency. I think in either 1836 and/or 1840, he had received some faithless electors electoral votes for Vice President. It might have been only 1.
But, he was nominated and elected in 1844. He didn't even seek re-election in 1848. And excluding all the Presidents who died in office, James Polk had the shortest-lived post-Presidency.
Jimmy Carter has the longest and as of September 2012 has surpassed Herbert Hoover to become that.
Given I'd not heard of him, I'll suggest he can't have been all that bad.
