This whole thing is kind of stupid. Its the libs in the lib states pushing this. The only way this will have a net effect in their direction is if their state votes for the Republican and the dem wins the overall vote. As long as none of the conservative states are stupid enough to join in I don’t see how this does anything but help conservatives.
The big risk is in a close popular vote tally, truck loads of ballots could be found in safe Democratic states to push the Democrat to victory. How can you argue with 25 million Illinois voters all voting for Obama's relection. Most years Illinois counting wouldn't affect the national result (1960 being the notable exception), but it would under this new plan.
