He should not even worry about the MSM.
I think McCain’s timing was a little off. The time to make this announcement was 5:55pm ET, not 2:55pm ET. That way it would have taken over the evening news and Obama’s dithering would have been palpable. As it is, as long as Obama has a position by 6pm, the MSM will have time to completely recast the matter in Obama’s favor.
