This is brutal. The rumors were thick yesterday, but it hit. Ambassador Richard Blackenship, a major Florida donor, switched from Romney to Giuliani. Check out part of the letter:

"The changes in core beliefs gave rise to some concerns. You have to have an anchor in life," he said of Romney. "Mayor Giuliani has a firm, secure hold on his moral compass and how that effects his platform, rather than change to satisfy special interests in our party. The Republican Party needs to broaden its appeal beyond a few special interests."

[Blackenship] said he resigned from Romney’s Florida finance team after becoming convinced Giuliani had broader appeal and said other Romney fundraisers in Florida could do the same.
