Election Day is more than a year away, but the field of most competitive Senate and House races is already starting to take shape. While the political environment could change over the next 17 months, the landscape is largely set as a handful of races in each region will likely decide the majorities in the next Congress.
The fight for the Senate is likely to be decided in the Midwest, where Democrats have takeover opportunities in Illinois, Wisconsin, Ohio, and a longer-shot opportunity in Indiana. If Democrats can win three out of those four states, they will be well on their way to gaining enough seats to take control of the Senate.
