Cause and effect?
Mail in voting, allowing counting ballots after election deadlines, only voters at the polls requiring ID, (Which looks good but does not address mail in ballots potential fraud) leads to effect- Dem wins?

Election Reforms, Vote by Mail Option became Law
Election reforms passed as a result of the close Gubernatorial Race of 2004. For example, voters voting at the polls were required to show ID, and election administrators were provided additional time to process ballots after a general election. In addition, counties were given the option of conducting elections entirely by mail, resulting in more than two- thirds of the counties switching to this method of voting.
"election administrators were provided additional time to process ballots after a general election"
Then, by 2011 I believe:

"While 28 states offer mail-in ballots, just five currently conduct elections entirely by mail — Colorado, Hawaii, Oregon, Washington and Utah."
