Why on earth would he try?
What is possibly in for Obama to cancel the elections? Jesus, people. This crap is so silly.
Here's what Barack Obama is going to do. He will leave the White House peacefully on January 20th. He won't pilfer the china or silverware. He's actually above that. In the next couple of years, he'll get his wife elected Senator in a safe blue state, create a slush fund disguised as a charitable organization to sell political influence, and become wealthy beyond his wildest dreams. A dozen or so years down the road, Michelle will campaign as the United States' first African-American female president.
He's learned from the best.
Say maybe you just answered your own question there. ;)
