Romney plunks down $4.5 million on new buy

NBC's Domenico Montanaro reports that Mitt Romney's campaign is going back on TV after an 11-day blackout, and is spending $4.5 million on ads that will run in Virginia, Ohio, Florida, Colorado, Iowa, New Hampshire, Nevada, and North Carolina.

It's interesting that Nevada made the list and not Wisconsin, considering that Obama has led in every Nevada survey this year, while Romney has led in two of the last four Wisconsin polls, and only trails by 1.4% in the RCP average.
