i think we've found the absolute bottom that bush's approval rating could possibly sink to:
the cnn poll, conducted april 21-23 by opinion research corporation, found that only 9 percent thought the u.s. mission in iraq had been accomplished, while 40 percent believed it would be complete someday.
that's 21 points to go. at its current trajectory, an average of one point per month, his numbers should hit 9% in february 2008.
(and if that 9% ever wakes up, bush'll hit zero just in time for the 2008 elections!)
(hat tip to think progress.)
