The state legislative selection of Senators is in essence the same as the Electoral College selecting of the president. We would in many cases eliminate the popular vote of the big cities.
I don't know about that, but I know that we would counter the massive voter fraud that occurs in some of those big cities. In some places, it's pretty easy to drive from precinct to precinct voting in the name of the newly deceased. Especially where no voter ID is required, and where precinct workers are sympathetic to the cause (can you say "democRAT" - I knew you could).
