Bait & switch  

Taegan Goddard brings up an issue I've been wondering about in re the US Senate race in Illinois: what happens if a candidate drops out between now and the election? The word around the campfire is Jack Ryan's divorce papers hold some revelations that (assuming they come out) will torpedo his campaign. While Obama is taking the high road so far, Republicans are clearly worried this stuff will become public sometime before November, and as Rick Hasen points out, we may see some interesting constitutional battles over how a replacement candidate should be selected.
