"We Face Formidable Challenges"--Just in the Primary

In a surprise decision, Sen. John McCain has announced he'll seek the presidency.

McCain's announcement comes one day after a new Cronkite-8 Poll by ASU Prof. Bruce Merrill shows that McCain has slipped from 44 percent to 32 percent among Arizona Republicans. Not exactly good news in your ostenstible home state, but these are early numbers that remain soft because the candidates have not yet begun to fight.

Also:

George W. Bush's approval rating has hit a new all-time low of 36 percent. Nearly one-third of voters surveyed say that Bush will be remembered as one of the worst presidents in history.

Just more than half--51 percent--tell pollsters there should be a timetable for leaving Iraq, while 42 percent were opposed to the idea.
