Charlie Crist offered his support today for Elena Kagan, saying he's "impressed" with her so far.

"What I have been able to read thus far I'm impressed with," he told the Miami Herald editorial board. "If I had to vote today, I would vote to support her."

But pressed to explain why he would support Kagan but opposed Sonia Sotomayor while he was a member of the Republican party, Crist was at a loss for words.

"To be honest I can't recall it right now," he said. "It had to be a ruling she had previously."
