Anti-incumbent mood sweeping country in troubling sign for GOP majorities

A sour, anti-incumbent mood is sweeping across the nation on its 250th anniversary in what political analysts say is an especially troubling sign for Republican control of the House and Senate, given President Trump's slumping approval rating.

Rising voter anger with the status quo has hit both parties, with eight House incumbents — five Democrats and three Republicans — losing primary races this year in addition to two GOP Senate incumbents, Sens. Bill Cassidy (La.) and John Cornyn (Texas).
