A new survey of over "60 influential Republicans" in Missouri has Marco Rubio emerging as the favored one for vice-president.
The results:
1. Marco Rubio 31%
2. Condoleezza Rice 23.8%
3. Paul Ryan and Bobby Jindal 11.9%
5. Tim Pawlenty 9.5%
One person (good for 2.4%) picked Rob Portman.
Is this meaningful? Not on its own, necessarily, but it's another data point suggesting that Rubio generates the most enthusiasm among activists.
