So who is going to be on the ballot instead? I hear weird rumors about the (de facto) Republican candidate, but haven't heard much else.
There is only one Republican on the primary ballot, and he's a crazy, but there's a write-in campaign supported by all the powers that be. Write-in for the primary, that is - if they win their candidate will be on the ballot (and win) in november.
By the Democrats as well? Don't they have their own candidate who could possibly win?
The Powers That Be are Republican.
This race is (probably) over once the primary ends with a write-in win. How certain that is, I dunno, but I guess. Basically, an "keep an eye on but assume R hold" type of seat.
Ah, I see; so who's the most likely candidate for a write-in campaign? I checked, and it seems that the Democrats have an honest-to-goodness/terribleness LaRouchite named Bill Roberts and a random doctor named Syed Taj running, so it doesn't seem they have a chance.
