Now that all states have concluded their congressional and gubernatorial primaries, Daily Kos Elections is please to present our guide to the demographics of every Senate, House, and gubernatorial nominee in the country. This spreadsheet contains the race, gender, age, religious affiliation, LGBTQ status, and even a name pronunciation guide for every candidate whom our race ratings give a chance to win in November, and it also includes the our calculations of the 2016 and 2012 presidential results by House district. We'll continue to fill in this spreadsheet as we come across new data, and you can find similar demographics for the current House and Senate members in our 115th Congress guide.
Democrats have a nominee in 432 of 435 congressional districts, the most they're contesting since the 1974 Watergate wave, when Team Blue had a candidate in all but a single district. On the other hand, Republicans have left 39 House seats without a nominee, and such a large disparity historically points to a Democratic wave environment this fall. Note that these figures include Louisiana, which holds a "jungle primary" on Election Day that goes to a runoff if no candidate takes a majority.
Meanwhile, one of the most important stories of the Trump era has been the astonishing surge in the number of Democratic women running for office. Including top-two general elections between the same party, 185 Democratic House candidates are women, which is 42 percent of their total. Once you exclude Democratic incumbents, a full half of Democratic candidates are women, including in half the race that Daily Kos Elections rates as Tossup. By contrast, only 52 Republican candidates are women, which is just 13 percent of their total. Consequently, 2018 is poised to set a new record for the number of women and people of color in Congress, thanks to likely Democratic seat gains.
