Question

It is widely believed in GOP circles that Mark Gundrum will run for AG. If so, he will have to give up his seat.

Furthermore, if TABOR doesn't get passed, it is very likely that someone will challenge Lazich in the primary (and win). If Gundrum goes for AG, he can't be that challenger.

In an exercise of pure speculation, who will step up to replace Gundrum if he runs for AG? For bonus points, who will challenge Lazich (is that why Stone is making so much noise)?
