Ohio: William Ayers

The American Issues Project, a 501 (c)4 organization representing a coalition of conservative activists, is up in Ohio and Michigan Thursday with a substantial $2.8 million advertisement buy that hits presumptive presidential nominee Sen. Barack Obama (D-Ill.) on his connection to 1960s and 70s-era radical William Ayers.

The ad buy is the largest third-party expenditure to date in this election cycle.
