EDIT: Plus it is mostly about creating the market and not just about each individual car.
Buying an EV is one thing, being able to drive it beyond city limits another...
Additionally when a coal plant is taken off-line in favor of hydro, solar or wind it has a very large impact on the local power companies %. The 19% change Robert is talking about is a national trend. EPA rules also are now in place to apply the Clean Air Act to coal power production, <snark>it only took 20 years </snark>, so this will accelerate not deaccelerate. Coal plants will also work to lower their emissions with scrubbers which again benefits EVs vs ICE vehicles.
Even if your EV is only as clean as a 40 mpg highway ICE, that's still not bad and as was said above, it should get better over time due to the amount of coal power likely going down over time. You also have the option to install solar panels, buy wind energy down the road...etc to indirectly offset your use. Also, at a minimum, you shift the pollution from your car to the power plant and farther away from a population center (most likely).

Also the mechanical condition of the ICE car will deteriorate with time and cause additional pollution. While the electric car's mechanical condition may also deteriorate, the deterioration is not likely to cause the same amount of extra pollution. And in many areas the "pollution check" is kind of a joke.
Sufficiently advanced magic is indistinguishable from a rigged demonstration.

JRP, that conclusion has been rebutted. There was a good reference to the rebutting report posted elsewhere on these forums, but the net takeaway is that NG is still far better than coal. (Also remember that coal mining often releases trapped methane gases, which are not captured.)
