BAsically, as I understand it (!) the electors of the USA elects "electors" to the Electoral College - each state has a no. of electors equal to its number of Senators + memebers of the House of Representatives - the Parties provide party "slates" in each State which is what the electorate vote for: e.g. if the people of Texas want to vote for Bush, they will elect electors from the Republican party slate who will then vote for Bush i the Electoral College - which is a "concept" rather than an actual college building! Thre's more to it than this I don't doubt, but I think that's the gist of it.
