The big story of the upcoming midterm elections will be the fight over which party will control the U.S. House of Representatives during the last half of President Donald Trump's second term in office. But there's a related issue that is potentially just as important — whether the Trump administration will try to interfere with the way the elections are held. Democrats point to a number of developments over the past year as warning signs. Trump has issued executive orders on voting and targeted groups that organize and fund Democratic campaigns. His Justice Department has sued mostly Democratic-controlled states for detailed voter information. And the administration has sent the military into Democratic-run cities.
