Mitt Romney: Nuanced Positions, or Flip Flops?

The independent website Factcheck.org looked at the Democratic National Committee's ad on Mitt Romney, and found of 15 claims, 9 were untrue, 5 were true, and one was half-true:

Flipping Through DNC Playbook on Romney. The fact-checking article cites several examples of nuanced positions that Romney has adopted that could easily be considered muddled, but probably not flip flops. One wonders if the DNC did their homework on this ad or is just flinging everything at the wall and hoping something sticks.  The playbook from Pres. George W. Bush's campaign in 2004 appears to be on display -- labeling a potential opponent a flip flopper early and often was enough for Pres. Bush to win re-election despite his own personal unpopularity, so maybe it will work for Pres. Obama, too.  We shall see if this "character" (ad hominem) approach works or not.
