Muslims are fairly likely o lean Democrat considering war on terror and all. Keep in mind however that the vast majority of American Muslims are black and the vast majority of American Arabs are Christian. Just so you know.
Seriously, if the candidates are similar to this time I expect little movement. States won by Kerry that will be battlegorunds are PA and WI, on the other side I see NV, CO, IA, FL, OH. That gives a base-line of 223 R EVs and 221 D EVs. WIthout a major land-slide for one side or a significant change in the platforms from this election that's how I expect it to turn-out.
