The AP reports that Hillary Clinton met with Barack Obama in Chicago yesterday, adding fuel to speculation that she might be Obama’s choice for secretary of state. If that happens, it has long been rumored that Brian Higgins would be appointed to her Senate seat. (BuffaloPundit reports that rumor this morning. And again this afternoon.) I know a couple prominent businessmen who are working to make that happen, and who knows? Downstate Democrats will make that decision, but maybe it’ll come to pass.

If Clinton does go to Obama’s cabinet, and Higgins does take her Senate seat, then who fills Higgins’ spot in the House? Byron Brown has had his eye on Louise Slaughter’s seat, should she retire soon. But Higgins’ seat is probably safer for Brown (for whomever winds up in it, hypothetically). After the 2010 Census, upstate New York is likely to lose another representative in Congress, and Slaughter’s seat might be the one to go. It’s one ugly-looking district:

There has been another rumor that Brown, not Higgins, would be appointed to Clinton’s seat, but that seems nutball. Higgins’ seat seems a more reasonable aspiration for the mayor.

Who, then, would join Mickey Kearns in the race to replace Brown next year?
