LOS ANGELES (AP) — Primary elections in seven states Tuesday will set the stage for U.S. House and Senate battles this fall that will play into control of Congress. Many contests are being shaped by political divisions in both major parties — and the lingering shadow of former President Donald Trump. A string of Republican House incumbents are contending with challenges from the political right. Some challengers are embracing Trump's baseless claims of election fraud in his 2020 loss to President Joe Biden. No incumbent governors or senators appear to be in imminent danger. The primaries are in California, Iowa, Mississippi, Montana, New Jersey, New Mexico and South Dakota.
