James Polk was the 11th President of the United States of America. He is best known for taking a hardliner anti-immigration stance, responding to repeated incursions by the Mexicans into California, Arizona, New Mexico, and Texas by invading Mexico and taking those territories for the glory of America. He then turned them all into states, although Texas actually declared itself an independent republic for a while. Many Texans still believe that their state is an independent republic.
In spite of all these things, Polk was a Democrat. Any attempt at conservatism was rendered moot when he was discovered penetrating the young Italian chef in the White House kitchen in front of the sink and next to a tub of Vaseline.
Protested Polk, "Hey, Mexico can't be the only thing I'm allowed to invade, can it?"
