Although the national political media establishment has moved on from Florida to the West, Marco Rubio will continue to be a major presence throughout the year, as speculation focuses on him as a potential vice-presidential nominee.

During the past couple of weeks in Florida, interest in how Hispanics might vote was a prominent theme, and Rubio was frequently called upon to express his views — which are quite conservative on the issue of illegal immigration.

And that puts him to the right of many Latino advocacy groups. An ad slamming Rubio for those views is airing on cable news on Friday in the Sunshine State.
