Five key races and issues to watch in Tuesday's midterm elections
Source Summary
Midterm elections are typically referendums on the party in power, and this year President Donald Trump has urged Republican voters to treat the race as a referendum on his leadership. Trump's declining poll numbers, attributed to cost-of-living concerns and an unpopular war, have created a political environment that favors Democrats.
Why it matters
Midterm elections determine control of Congress and shape the legislative agenda for the remainder of the presidential term.
