In election news, Arizona Senator John McCain has officially entered the race for the Republican presidential nomination.

Sen. John McCain: “My friends, we face formidable challenges. I’m not afraid of them. I’m prepared for them. I’m not the youngest candidate, but I am the most experienced.”

McCain drew criticism last week for joking about bombing Iran. When asked about whether the U.S. should attack Iran, McCain began singing “Bomb, Bomb, Bomb Iran” to the tune of the old Beach Boys song “Barbara Ann.”
