Some incumbent lawmakers are facing each other in primary elections in two states Tuesday. The intraparty battles are in New Mexico and New Jersey.
The race to succeed retiring New Mexico Senator Pete Domenici pits five-term Republican Congresswoman Heather Wilson against three-term GOP Congressman Steve Pearce.
Pearce represents a conservative district and has labeled Wilson a liberal. Wilson has a reputation as a moderate and counters that she's a common sense conservative.
Congressman Robert Andrews bucked his party leaders by deciding to challenge Senator Frank Lautenberg for the Democrats' Senate nomination in New Jersey after initially saying he wouldn't.
The 50-year-old Andrews has focused on the fact that Lautenberg is 84. Lautenberg touts his effectiveness as a senator and that Andrews co-authored legislation supporting the war in Iraq.
