1. The whole electorate can focus on just this race, since it is a runoff
2. It will be harder for the media to obscure irregularities in LA because of #1
3. The Dems have already lost Sentate majority status, so they have to weigh the risks of voter fraud in this case
4. Because of Landrieu's shennanigans last time, local parishes are watching very closely
I still think there will be massive attempts at corruption. But, we will have to see.
