For long-time Republican Matthew Higgins, the moment of truth came when his nine-year-old son came to him with a question.
"'So daddy, is this how the political process works?'" said Higgins, recalling his son's query one evening. "'If you're a member of the Republican Party, does that mean you have to vote Republican, even if you don't agree with what the Republican is saying?'"
Higgins is CEO of a company called RSE Ventures, but he was press secretary when Rudy Giuliani was mayor of New York and was involved with fundraising for the McCain and Romney campaigns.
