(CNN) - Though all 435 seats in the U.S. House of Representatives will be up this November, the battle to control the chamber next year will come down to a much smaller number of congressional districts scattered across the country. CNN has identified the top 100 House races, which we’ve dubbed “The CNN 100,” and will profile one of these races at random each day for the final 100 days leading up to the election. These seats run the gamut both politically and demographically: red states and blue states, urban and rural, open seats and seats with incumbents facing their first competitive race in years. Some are highly competitive, while the race is still developing in others. We’ve listed the CNN 100 below in two groups: the 50 most vulnerable seats, and another 50 races worth watching.
