Pure unadulterated BS. Doing the vote by congressional districts means that the presidential vote can be gerrymandered. I have for years been quite taken back by the fact that many conservatives seem to think that congressmen represent land mass, showing maps of huge expanses of land colored bright red, with those small islands of blue that dictate how all those country folk must live. Yes, it is hard to accept that a lot of people live in cities and that their votes for Democrats "cancel" out those red votes out in the countryside.
I know you all hate Maddow, but she did an interesting story on what gerrymandering did to the congressional outcome in many battleground states. Now that Democrats can garner the majority in a state overall and get slaughtered in the ratio of blue-to-red in the congressional delegation, you all want to extend that to the presidential election. No amount of outright and obvious underhandedness and cheating shames them.
