Harsh GOP robo-call hits Ayers

A harsh new robocall (above) — at least the third in a series — attacks Obama for having "worked closely with domestic terrorist Bill Ayers" whose group "killed Americans."

Robocalls are a relatively inexpensive way to deliver a negative message, and used to be seen as an under-the-radar way to do it, though that's no longer really true. The ad comes just hours after McCain dismissed the issue: "I don't care about an old, washed-up terrorist," he said.

The script:

Hello. I'm calling for John McCain and the RNC because you need to know that Barack Obama has worked closely with domestic terrorist Bill Ayers, whose organization bombed the U.S. capitol, the Pentagon, a judge's home and killed Americans. And Democrats will enact an extreme leftist agenda if they take control of Washington. Barack Obama and his Democratic allies lack the judgment to lead our country. This call was paid for by McCain-Palin 2008 and the Republican National Committee at 202-863-8500.

I spoke to women who got the call in Wisconsin and New Mexico, and a Democratic official said they'd also had reports of it in Northern Virginia, Maine, Florida, Missouri, and North Carolina. Other readers report getting the call in Ohio and Indiana. Shaun Dakin has a report from Pennsylvania.

Greg Sargent has reported on two earlier calls.
