It's pretty simple, really.
There is a long history in Presidential elections, and the Muslims are not stupid -- The American people typically will not change a President during a significant armed conflict or other time of material international disruption.
Think about it.
And then consider this -- Obama is as about as friendly to radical Muslims as a US President could ever be without inviting them to the White House for his daily security briefings and giving them the keys to our arms depots.
So we have escalation now, with the intent of drawing in the United States and driving outrage here at home.
If that is achieved, the bet is, the American people will not "take a risk" with Romney.
