Massachusetts Republicans will pick their nominee to challenge Sen. Elizabeth Warren on Tuesday, but only two of the blue state’s nine House incumbents will face challengers in November.
In addition to picking a Senate nominee, Republican voters in the 8th District will choose between three candidates to take on Rep. Stephen F. Lynch on Sept. 3.
In the 9th District, Republican Dan Sullivan, a registered nurse, is unopposed in his primary to challenge Rep. William Keating.
