In between private sessions at the Four Seasons hotel with GOP stars such as Louisiana Gov. Bobby Jindal, Sen. Rand Paul of Kentucky and Sen. Marco Rubio of Florida, many attendees expressed concern about the strategy of tying funding of the government to measures that would stymie the president’s health-insurance initiative.

“People are totally annoyed,” said one attendee at the Crossroads meeting who asked not to be identified, to discuss private conversations.

The frustration was evident this past week not just at the Crossroads conference but also throughout the party’s high-end donor class. While grass-roots activists cheer the unyielding positions of conservative House Republicans, some of the GOP’s top fundraisers are watching the situation with growing dismay.

“I oppose Obamacare as much as anyone else does, but this is not the way to repeal it,” said Bobbie Kilberg, a longtime GOP donor and fundraiser in Northern Virginia.

“The fact is, donors have had it,” Kilberg added, saying she will not give donations to groups raising money broadly for House or Senate Republicans. “I will only give to individual candidates who get it.”…

“There are a lot of major donors who feel that until the Republican party can field people who have a vested opinion of what to do and to do it in a prompt and efficient way, we’re going to withhold giving money,” Hoffman said, adding that the donor freeze could affect “a lot of current far-right Republicans.”
