Mitt Romney agrees with the Supreme Court ruling that says the Obamacare mandate is a tax. Obamacare's mandate is absolutely a tax, Romney says. However, he wants you to know that Romneycare's mandate is definitely not a tax:

“The chief justice, in his opinion, made it very clear that at the state level, states have the power to put in place mandates. They don’t need to require them to be called taxes in order for them to be constitutional. And as a result, Massachusetts’ mandate was a mandate, was a penalty, was described that way by the Legislature and by me, and so it stays as it was,” he said.

It's the same thing, but it's different because it's at the state level. Therefore, Obama raised taxes and Romney raised none, even though they did the same exact thing. Get it? And Romney is against mandates now...except he's not. Buzzfeed found a video of Romney saying he likes the federal mandate:

Mitt Romney's truth is everyone else's equivocation. I especially like his preamble in the above video, which is vintage Romney: A finely chopped word salad in which he says the most obvious thing in the most bland language possible: "There are some similarities, and there are some differences. I like some of the similarities, I dislike most of the differences."
