Sen. Marco Rubio visited Your World yesterday for a lengthy interview. Host Neil Cavuto asked about Obamacare “and maybe defunding it” to get “closer in line with that libertarian point of view espoused by Senators Lee and Cruz and others who argue that in the case of Obamacare, just defund it. That’s something that you hadn’t been talking about months ago, but now are leading an uphill fight to make it happen now.”

Rubio said, “Well, actually, Neil, I campaigned on repealing Obamacare. And what I’ve said now is that we had all hoped the Supreme Court would’ve thrown it out. We’d all hoped that an election would’ve elected a Republican President, would’ve helped us repeal it, that didn’t happen.”

Cavuto replied, “But Even Senator Cruz says this is unlikely to happen. That he thinks it’s got an uphill fight, this defunding effort.”

Rubio answered, “It is, but I think we can still win it. Because quite frankly, what other choice do we have but to fight on this issue? If Republicans and conservatives are not going to draw a line in the sand on this issue, if we’re not willing to say this is the issue we’re willing to fight to the end on, then what issue are we willing to do that on? …Americans are going to start losing their existing coverage. People are already being moved from full-time work to part-time work because of Obamacare.”

In fact, the data suggests that the trend toward part-time work predated Obamacare and is a function of the economy and not an avoidance of health insurance coverage. But Cavuto didn’t mention that. He did, however, suggest that Republican efforts to defund Obamacare are misguided. “But if you can’t defund it, then you’ve wasted your time, right?”

Rubio countered, “I think we can definitely defund these exchanges which are already turning into a disaster. Just moments ago, I saw a news report, the state of Ohio is reporting that the individual market in Ohio, the premiums are going to go up by 40%. In my home state, a report two days ago by the insurance commissioner, the premiums are going to go up 30-40%.”

Well, at the very least that’s debatable. And there are states, such as New York, where the cost of premiums has been lower than expected, thanks to Obamacare. Not a word about that from Cavuto, either.
