Asked during an MSNBC town hall whether he would be open to that, Rubio was firm.

“I think that’s kind of House of Cards stuff,” the Florida senator said.

“It looks good on TV, it doesn’t ever work that way. Bottom line is, you know, this process is going to play itself out,” Rubio said, emphasizing that his campaign is focused on Florida. He then cautioned against lofty expectations in other states voting Tuesday, “So, don’t be surprised if we don’t do well in some other states next Tuesday because we’re not there. We’re here.”
