It’s Primary Day in Maine, Nevada, North Dakota and South Carolina. In Nevada, Republican voters will be deciding who will challenge Democratic Senator Catherine Cortez Masto in November in a race that could decide who controls the Senate. The Republican Senate race pits former Nevada Attorney General Adam Laxalt against retired Army Captain Sam Brown. Laxalt is a close ally of Donald Trump who supported Trump’s efforts to overturn the 2020 election. A number of other Republicans who supported Trump’s coup attempt are also on the ballot today.
