Ad Wars: McCain Campaign Lauches Web Ad on ACORN, TV Ad on Ayers

With just 25 days left until Election Day, the airwaves and Web video are getting increasingly cluttered -- and increasingly ugly.

U.S. Sen. John McCain's campaign has two new guilt-by-association ads out, both questioning U.S. Sen. Barack Obama's motives and judgement.

One, a new Web ad, seeks to tie Obama to ACORN, a community organizing group under investigation for voter fraud. The McCain camp held a conference call today with reporters today to call for a federal investigation of Obama's alleged ties to the group. The ad does away with any such niceties and makes its own assertions:

The New York Times, which calls the second McCain spot "...a paint-peeling advertisement that highlights Mr. Obama’s relationship to Bill Ayers, one of the Weather Underground founders," reports: "The campaign says the commercial will air nationally. So far this morning, using the television monitoring service ShadowTV, we have found that it has only been shown by news programs — once on MSNBC and once on WINK-TV in Florida – and has not run yet as a paid commercial."
