Primaries in Maryland and West Virginia will shape the battle this fall for a Senate majority

Voters across Maryland and West Virginia will decide key primary elections with big implications in the fight for the Senate majority this fall. At the same time, Democratic President Joe Biden and Republican rival Donald Trump hope to project strength in Tuesday's low-stakes presidential primaries. Further down the ballot, two congressional candidates on opposite sides of the 2021 Capitol insurrection serve as a stark reminder that the nation remains deeply divided over the deadly attack. In all, three states are hosting statewide primary elections Tuesday — Maryland, Nebraska and West Virginia — as Republicans and Democrats pick their nominees for a slate of fall elections.
