Green Party spoiler candidates in PA-07/08 threaten Dem flips; PA Medicaid cuts become wedge issue; gubernatorial races in PA, WI, IA, CO could affect House math. Michigan primary preview: MI-07 (Brink vs Maasdam vs Lawrence) and MI-10 (Hines, Chung, Greimel) primaries days before Aug 4 vote. Sabato's Crystal Ball shifts 13 House races toward Dems, including PA-08, NY-17, NC-11 to Tossup. Texas Senate race tightening adds to GOP danger; El-Sayed and Hong as progressive bellwethers.
