Mixing politics and religion

Have I mentioned before how pissed off I get when people invite agenda-pushing politicians into church? Here's my favorite exploiter Rev. Jesse Jackson preaching at Riverside Church:

"Whose god is God? There is a profound theological debate in our nation tonight about the nature and character of God. . . . Today the Congress reconvenes to save a woman — Terri Schiavo — from starving to death, but then votes to starve millions every day. Whose god is God? They fight to save the fetus, and then starve the babies. Whose god is God?"
