After fueling the success of Sharron Angle in Nevada and the near (or pending?) success of Joe Miller in Alaska, having spend hundreds of thousands of dollars on each, Tea Party Express says it is prepared to set its sights on Delaware, where moderate Congressman Mike Castle is running for Senate, facing a primary against the conservative Christine O'Donnell on Sept. 14. The Hill's Shane D'Aprile reports:

Tea Party Express spokesman Levi Russell said Monday that his organization is already cutting TV and radio ads in Delaware and expects to be on the air by the end of the week. Russell said he hopes to match the support the group offered in GOP primaries in Utah, Nevada and Alaska this year.  

"All of our spending is dependent on the enthusiasm of the Tea Party Express members," Russell said. "It's up to that race and that candidate to capture their imagination."

Tea Party Express has spent just over $587,000 in support of Miller, as of its latest Alaska-related financial disclosure late last week. It had spent just over $537,000 in support of Angle as of August 4.
