Rep. Michael Castle, R-Del., and the Tea Party Express purchased more airtime late Tuesday for what is shaping up to be a nasty run up to next week's primary. Castle bought another $75,000 of airtime in the Salisbury, Md., market, which covers southern Delaware, according to a Democratic source. The Tea Party Express, which is backing GOP primary candidate Christine O'Donnell, purchased $32,000 for air time on cable, but only in the Salisbury market. Both ad buys start today and run through primary day on Tuesday.
The ad buy brings Castle's total spent on the air in the primary to about $250,000. The Tea Party Express has vowed to spend $250,000 on the race, but it looks like it may be difficult for them to reach that goal before the primary. The largest estimate, including radio and direct mail spending, comes to just less than $138,000. Castle also went on the air on Tuesday with a negative TV ad targeting O'Donnell for tax issues and defaulting on her mortgage.
