But for some reason when Republicans face primary challengers from the Right there's barely a whisper. At least Ron Brownstein is going to mention it.
This ideological inquisition among Republicans isn't confined to the presidential race. The two House Republicans most critical of the Iraq war (Walter Jones of North Carolina and Wayne Gilchrest of Maryland) have drawn serious primary challengers from the right. So had Nebraska's Chuck Hagel, the Senate Republican most critical of the war, before he announced his retirement last month. Virginia Republicans recently decided to choose their next Senate nominee by convention rather than primary -- a move that favors conservative former Gov. Jim Gilmore over moderate Rep. Tom Davis.
