The notion that Romney would have won under a different electoral college system is dubious.

2. But how you allocate resources would totally change. The Repugs could have even lost the House...

Think of how it works in the current system. Take Ohio for instance. It's always a toss-up, so both sides naturally throw a lot of money their way. But since the electoral votes are assigned winner-take-all style, each side does what it can do drive up their statewide vote totals the most - for Obama that meant GOTV in Cleveland and Columbus and Toledo. For Romney that meant doing the same in the well-to-do suburbs. No regard was paid to which congressional district these voters lived in.

Change the electoral system to congressional districts, and suddenly Team Obama will be in the suburbs right alongside Team Romney, making for a much closer race in many of those districts that are supposedly safely Republican. The cities would be ignored by both sides, as both sides recognize Obama's got them in the bag.

Again, I'm not saying this would be a good development for democracy - not at all. But it would change where - and how - the battles are fought. And the election results might even end up surprising Repugs, in a bad way.
