Mark Ortiz is running for congress in the 8th district, making a total of four Democrats looking to claim Hayes's seat (if we count Lloyd Scher, who we haven't heard from in a while). I'm sure we'll all be learning more about Mark in the coming days and weeks, but it sounds from his announcing press release that his central issue is the war. He's against it.
I've copied the full text of the press release below, but first let me offer this fortune-cookie message: only one of these guys is going to be the official Democratic nominee. I think so far we can assume that each is running because he loves his district and his country, and to get a chance to go to congress, they have to argue and pick at each other. That's a good thing to the extent that it generates informed debate about the issues and enhances the winning candidate's understanding of the people of the 8th; it's a bad thing to the extent it gets ugly and balkanizes the base.
