Obama is an illegal alien, and yet the DNC didn’t care, so if Rubio is on the ticket, do you think the left will attack him? go ahead and let them, the Hispanic community will turn against the Democrats if they try to bash Rubio. And hopefully we will have the Dream Ticket of Perry/Rubio. Even Perry/McDonnell sounds terrific.
Rubio is young, good-looking, articulate, popular in the swing state of Florida and able to effectively communicate a conservative message to the voters. If he throws his hat into the ring, he'll be attacked mercilessly because he is that rare but serious threat to the Democrats; an electable conservative.
