Politico reports that U.S. Sen. Jon Kyl is set to retire:
Senate Minority Whip Jon Kyl will announce Thursday that he is not running for reelection in 2012.
The second-ranking Republican in the Senate is expected to make the announcement at 12 p.m. ET from his home state of Arizona.
A source close to the senator confirms to POLITICO that Kyl has decided not to run for a fourth term. His departure opens up a major GOP leadership slot.
The news site follows up with the GOP leadership scramble in D.C. We'll also see a lot of dominoes fall in Arizona, as Republicans move to replace him. Expect Congressman Jeff Flake to run for Kyl's seat, which will set off another scramble for Flake's congressional seat among legislative Republicans, who are already angling for a ninth congressional seat.
As for the Democrats: Well, they don't have much a bench, do they?
