Tea Party Express's First TV Ad in Delaware

Tea Party Express has shaken up more than one Senate race with its simple yet effective TV ads this year. Delaware's Republican primary could be next.

Moderate Republican Congressman Mike Castle has led this race for most of the election cycle, and many assumed he would win in November, delivering Vice President Biden's former Senate seat into the GOP's hands. But earlier this week Tea Party Express endorsed his primary opponent, conservative commentator Christine O'Donnell, whom no one outside of the state knew much about, and whom the Delaware GOP vehemently opposes (Castle won he party's endorsement earlier this year).

Tea Party Express says it will try to spend around $250,000 to fuel O'Donnell's primary challenge in the final two weeks before the September 14 primary, devoting most of that to TV and radio ad campaigns.

Here's a rough cut (not yet final) of the first TV ad Tea Party Express will air in the state:

The ad goes after Castle for his low score by the American Conservative union and touts O'Donnell's opposition to "the bailouts" and deficit spending and her support for repealing Democratic health care reforms.

The ad is typical for Tea Party Express. It has run ads of similarly modest production value in Massachusetts, Nevada, and Alaska, backing the candidacies of Scott Brown, Sharron Angle, and Joe Miller. All of them won.
