He actually won a race recently, he's now a sitting state senator in Illinois and now he wants to be a US Senator. While I'm not sure he's a shoo-in he may well be a better candidate than many other's who have ran against long-time US Senator Dick Durbin in recent years.
BTW, I forgot to note earlier this year he was in charge of a push to oust a state party chairman for the GOP. While ultimately he appeared to back off the state GOP has a new chairman anyway and this was to enforce adhearance to the state GOP platform. All the same this state now has gay marriage anyway and it took a few Republican votes to get there as well.
