Bob Dold is definitely running in the 10th District, assuming that the proposed map remains more or less unchanged from the current proposal. I was getting a little concerned, as his decision hadn't received a lot of press, and as recently as yesterday I was speaking with some fairly connected folks who were unsure of what Bob was going to do. I spoke with the Congressman on the phone just a few minutes ago, though, and he confirmed that he's running in the 10th, regardless of the fact that his home was mapped out of the District by the Dems. I also found this article in which his District Director, Kelley Folino, confirmed that Dold in is. Kelley also confirmed that when Dold wins, he will move into the newly remapped district.
Well, at least he and Dan Seals have one thing in common now, i.e., they both live in the 9th District. ;-) But that's about where the comparison ends.
This is going to be a tough fight, but Dold can (and will) win.
