Republicans are already calling Obamacare the largest tax increase in history. This is not true—if you consider the mandate to be a tax, it's still lower than taxes raised by George H.W. Bush, Bill Clinton, and Ronald Reagan.

But lots of people are arguing that the mandate is not, in fact, a tax. One of the loudest defenders is Mitt Romney's senior adviser, Eric Fehrnstrom:

FEHRNSTROM: The governor believes that what we put in place in Massachusetts was a penalty and he disagrees with the court's ruling that the mandate was a tax.

TODD: But he agrees with the president that it is not — and he believes that you should not call the tax penalty a tax, you should call it a penalty or a fee or a fine?

FEHRNSTROM: That's correct.

I hate to bring up Michele Bachmann, but she and other Republicans claimed all during the Republican primaries that Mitt Romney would be unable to effectively attack President Obama on Obamacare because of his record with Romneycare. When Michele Bachmann turns out to be right, something is terribly wrong. When she's right about the weakness of a Republican presidential candidate, that might just be the makings of a disaster.

In other news, America likes a winner: As Steve mentioned in GMN this morning, new Reuters/Ipsos poll shows that the public's support of Obamacare has risen sharply since the Supreme Court's ruling.
