Sarah Palin’s negatives are skyrocketing.

As the steady drip-drip-drip of the public vetting of Palin takes its toll (since the impulsive McCain failed to do it himself), what people see they don’t like. She may be a delightful American Idol contestant, but as someone who is next in line for the nuclear football if 72 year-old Grandpa Melanoma takes the big hike, the public is a bit nervous.

Palin’s approval ratings are on the move:

Date Positive Negative Net 9/11 52 35 +17 09/12 51 37 +14 09/13 49 40 +9 09/14 47 42 +7 09/15 47 43 +4 09/16 45 44 +1 09/17 44 45 -1 09/18 42 46 -4

That’s a 21-point shift in 8 days. No wonder Rove is throwing her under the bus.

In her short tenure on the American stage, however, nobody can say she hasn’t left her mark.
