I wonder if Lipinski jumps in against Casten with Newman likely out of the way. My understanding is that this is a heavily Catholic district with lots of conservadems (I could be wrong though). If this is accurate, Lipinski could draw on a combination of his old voting base and using his Catholicism as a wedge against outspoken atheist Casten.
Marie Newman has been trying to get into Congress for years. She's not going to drop out because of an ethics complaint.
When has a silly little thing like corruption stopped anybody?
