It's Jennifer Rubin, what do you expect. She's been a Romney slappy for years.
While it's true Romney has a clear path to 270, Obama's path could be easier assuming the economy doesn't crash. Rubin seems to completely ignore the fact that Obama is actually sitting on around 246 near sure EVs (MI, Wis, NH and Pa are NOT swing states). Romney's best case scenario:

He basically has to win nearly every swing state to get there. Which would be possible if the economy begins to decline over the summer/fall
I used to think Bob McDonnell was the obvious VP choice but after the ultrasound fiasco he has to be toxic on a national scale. Rob Portman seems to make the most sense. Obama would certainly attack him for being Bush's budget guy but I doubt that will work; this is officially Obama's economy, there's no one left to blame but himself.
