Do you really think he was "sucked in?" Rubio was never really a conservative, but rather, a manipulator who understood how to appeal to the Tea Party and conservatives in order to defeat Crist and get elected to the Senate. From his perspective, his only mistake was a miscalculation on how much the amnesty issue would hurt him. In that sense, we are fortunate because we have seen his true colors.
Rubio is not a conservative nor is he some naive victim of McCain and Graham. Rubio thought this was the ticket to the WH--a Rep Hispanic who could garner Hispanic votes along with those of conservatives.
