As sort of predicted here, but not really: Tancredo didn't tell very many people before his announcement. He endorsed Mitt Romney.
And Rudy Giuliani is out of the hospital (or, "out of hospital," as they say in Britain), his somewhat elongated stay fueling plenty of speculation that he was sick... but the doctors were just waiting for all the tests to come back...various Giuliani sputum cultures and such... and he has a clean bill of health. A statement from his campaign:
"Mayor Giuliani is being released from Barnes Jewish Hospital with a clean bill of health. Doctors performed a series of precautionary tests and the results of all the tests were normal. The Mayor is heading back to New York this afternoon and he continues to be in high spirits."
