The electoral college is the most important check on State's rights. The electoral college gives voting power to smaller states and keeps states with larger populations from deciding elections and ultimately policy.
Why would a "State" need a "right". State's are imaginary entities. They only really exist on paper.
"Illinois" has never been over to my house for a cup of coffee.
What the electoral College does is take an election that should be run in all 50 states and lets about 10 states decide the election. It has a distorting view on what our problems are.
2004 SHOULD have been about how badly Bush fucked up the economy and the War. Instead it became about whether gays should be able to marry in Ohio. We're totally going to amend the constitution to keep them gays from marrying. Oh, ignore the fact Dick Cheney's daughter is a Lezbo!
