Primary elections in seven states Tuesday will set the stage for U.S. House and Senate races this fall, with many contests shaped by political fissures in both major parties and the lingering shadow of former President Donald Trump.
With control of Congress in play, a string of Republican House incumbents are contending with challenges from the political right, and some rivals 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. In Iowa, several Democrats are jockeying for the chance to take on seven-term Republican Sen. Chuck Grassley, with the campaign showcasing the breach between the Democratic Party’s progressive and establishment wings.
