Sweet: Conference call showdown looming Sunday. Axelrod, Gibbs (Obama) vs. Penn, Wolfson (Clinton)

HIGHLAND PARK, ILL.–Notices of dueling conference calls with the Obama and Clinton campaign heavyweights just arrived via e-mail. iWith Sen. Barack Obama (D-Ill.) working to clear his deck of Rezko and Wright issues, watch for his troops to crank up pressure on Clinton on the ethics fronts.

Obama’s camp came out first with a noon central time call with top strategist David Axelrod and Communications Chief Robert Gibbs. Then Clinton’s team teed up a call for 12:15 p.m. central time with pollster and adviser Mark Penn and chief spokesman Howard Wolfson. That’s the nightmare scenario for reporters, two important conference calls happening at the same time. The Clinton people just sent out a time change…they’re moving the time to 1 p.m.
