An easily overlooked poll, released during Palin’s announcement:

Ohio voters approve 46 – 42 percent of the job Gov. Ted Strickland is doing, according to a Quinnipiac University poll released today, down from 57 – 29 percent in a May 6 survey. This is Gov. Strickland’s lowest approval rating since a 45 – 12 score, with 43 percent undecided, February 1, 2007, one month after he took office . . .
U.S. Sen. Mike DeWine, a possible Republican challenger in the 2010 Governor’s race, has caught up with the struggling Strickland, with 40 percent to the Governor’s 41 percent, compared to a 48 – 36 percent Strickland lead May 6. Another challenger, former Congressman John Kasich, trails Strickland 43 – 38 percent, compared to 51 – 32 percent May 6. Kasich now leads DeWine 35 – 32 percent in a Republican primary, reversing a 35 – 23 DeWine lead May 6. Another 29 percent of GOP voters remain undecided.
