GOP donors to Crist: Where's our money?

“That letter went out today after we got the word,” said Sen. Johnny Isakson, Georgia Republican, whose political action committee contributed $1,000 to Mr. Crist’s campaign in June. “I do my PAC to help support Republicans.”

Sen. John Cornyn, Texas Republican and chairman of the National Republican Senatorial Committee, whose recruitment helped bring Mr. Crist into the race in the first place, said he hasn’t heard any decision from the governor. If a switch is in the offing, he said, he will ask for a refund of the $10,000 his political action committee has given.

“I suspect you’ll see a number of Republican senators ask for their money back,” Mr. Cornyn said.
