Despite receiving an implied endorsement from the White House as the preferred candidate, Marin was attacked by her fellow Republicans, in particular, former California Secretary of State Bill Jones, the leading candidate for the GOP nod, for her perceived waffling on another hot-button immigration issue: driver's licenses for illegal immigrants. Although she had opposed the state measure granting them signed by Gov. Davis in 2003, she refused to take a position on tough federal legislation to punish states that do so introduced by Congressman Tom Tancredo the same year. Marin was also passed over by key Republicans when Governors Schwarzenegger, her old boss Wilson, and George Deukmejian all endorsed Jones.
