Republicans are worried that Donald Trump, losing badly to Hillary Clinton, is dragging down the party’s candidates for Congress and state legislatures with him. Sens. Kelly Ayotte in New Hampshire, Richard Burr in North Carolina and Pat Toomey in Pennsylvania — once considered favorites for re-election — are now in tight races or losing. But presidential and Senate races are fought on the same terrain: state by state. Elections for the U.S. House of Representatives and state legislatures are more localized. So, how vulnerable are the GOP’s majorities in Washington and state capitols if Trump’s numbers stay where they are or worsen? CONT.
