It is backed by a $25,000 buy and will air for a week, starting Monday, on broadcast and cable networks in various Kentucky markets, including Lexington and Louisville, and in Washington, D.C.
PCCC is also airing the ad online, and will expand the buy as it brings in donations to do so via online fundraising, as it did with its first ad.
Including this buy, PCCC has now spent $100,000 on attacks in an early start to what's expected to be one of the nation's most hotly contested races in 2014.
