A "good" Republican for the Primary

For those of you registered Republicans, consider throwing your support behind Ron Paul. He seems like a very good candidate (I am not too hot on his immigration position, but then I don't have much detail). What a coup for liberty it would be if we could make him the Republican nominee. I have yet to learn of a good Democratic nominee. If there is one you like, let me know. As the campaign season starts to heat up, feel free to submit your picks and I will see about posting information about them.
