Exit polls show Republicans voted Obama too, but the majority of the readers I am hearing from went the Hillary route:

K-Lo Greetings from the great state of Texas. I am a conservative in Houston who voted for Hillary in the Texas democratic primary. I did not conspire with any fellow conservatives nor did I know that Rush was suggesting Republicans vote for Hillary. My goal is to have Hillary win the democratic nomination because I believe McCain has a better chance of beating her vs. Obama. Not that I am very happy that McCain won the Republican nomination. Why Hillary? Her negatives are much higher than Obama. If she beats Obama it will hurt her with the black vote. She will not get the “guilty white” vote like Obama. Hardcore Liberals are solid for Obama but might stay home if Hillary wins.
