It's still very early in the 2012 election cycle (heck, we aren't even really sure what the 10th Congressional District may end up looking like), but we're watching the Democrat would-be challenger (Ilya Sheyman) to Congressman Bob Dold, who came out earliest and seems to be getting the most press, with interest. He's as far left as you can get without swinging back around to the fascist/anarchists of the far right. And given that he's all of 25 years old, one might expect some hesitation on the part of general election voters to support such a candidate.
Just recently, a friendly interview of Sheyman was posted on the Chicago Magazine website. Sheyman toned down his politics considerably from the impression he left in a similar manifesto left on the Daily Kos website. Maybe he's already learning a little bit to cloak his progressive agenda with at least a patina of centrism to have some hope of broader appeal to the notoriously independent-minded voters of the 10th District. But you can still tell he's a dyed-in-the-wool progressive, with a liberal agenda that even President Obama would find it hard to embrace.
On balance, though, if I were Bob Dold, I would be crossing my fingers that the Dem field holds no more terror for him than this guy.
Bonus laugh: If you read the Chicago Magazine piece, Mr. Sheyman seems to believe (or wants to) that the Democratic machine (DCCC and minions/allies) will stay neutral in the primary and simply let the candidates sort it out with the voters, avoiding any favoritism. Well, if in fact Sheyman is correct, I would advise Debbie Wasserman-Schultz to wake up and go recruit a reasonable candidate, or all the trouble the Dems went to redraw this district (including redistricting Bob Dold out of his own district) will be for naught, if this kid ends up actually winning the Dem primary.
