How Will The Political Parties Change With No Electoral College?

[Smid]

I don't think the Christian Right or rural voters would split off and form their own parties, because there would be no chance of them coming anywhere near winning the popular vote - instead, they would be more likely to exert an influence over the Republican Party by threatening to stay home if they weren't enthused by the candidate nominated. Even the threat of starting a new party would probably have the GOP bending over backwards to appease them. In other words, basically what DC Al Fine said.

What you suggest might be possible if, rather than popular vote, the Electoral College were replaced permanently with Congress deciding on the President, or some other similar system.
