Trump's Final Two Years Hinge on Midterm Vote

U.S. voters head to the polls for the midterm elections, and the results could decide how much power President Donald Trump holds in his last two years in the White House. Midterms are elections held halfway through a president's four-year term. All 435 seats in the House of Representatives and about one-third of Senate seats are up for a vote. If the opposing party wins control of either chamber, it can block the president's plans and launch investigations. That would limit what Trump can achieve before his term ends. Here is what to watch as the vote approaches.
