I'm not a fan of federalism... and I detest state suffrage, the source of ALL the antidemocratic features of our system.
As for the EC... it seems more a ploy to get the slave states to ratify the Constitution. Here's Madison at the Constitutional Convention supporting the popular vote... BUT there's a problem...
The people generally could only know & vote for some Citizen whose merits had rendered him an object of general attention & esteem. There was one difficulty however of a serious nature attending an immediate choice by the people. The right of suffrage was much more diffusive in the Northern than the Southern States; and the latter could have no influence in the election on the score of the Negroes. The substitution of electors obviated this difficulty and seemed on the whole to be liable to fewest objections.:
I think we all know WHY the system is as it is... it gave every special interest invited to the constitutional convention a check on every other group. But lost in these cynical negotiations was the principle the nation was founded on... that the moral legitimacy of government is derived from the CONSENT of the governed. If the minority can govern through transparent tricks like state suffrage, it VIOLATES that principle. It also violates the what SHOULD be a key civil right... civic equality in the vote... to which I should add the right to vote one's conscience and get some representation for what one believes.
