At Daily Kos Elections, collections of elections data have always been our lifeblood, so we’ve corralled all of ours into this post to make it easier for you to find them. We keep this page continually updated, so bookmark it for future reference. You can also find it at dailykosdata.com.
We welcome (almost) any use of our data as long as you cite us and include a link to our work so that others may easily find it. However, we ask that you please refrain from reproducing entire spreadsheets in your own publications.

Election Results by Congressional & Legislative Districts.
All results were calculated by the Daily Kos Elections team following our extensively detailed methodology. We also have calculated what portion of old congressional districts is within each new district (redistribution tables). Our results are free to use, convenient to find, and transparently calculated, and have been widely cited in national media outlets and academia alike. We offer three types of tables:
Type A: lists results for all districts in one sheet
Type B: lists results for all states, with one state per tab; shows results by county
Type C: lists results for one state, with one county per tab; usually shows results by precinct
Table type shown in parentheses below.

Special Elections.
We have been tracking special elections results since the 2018 cycle, and include all congressional and legislative contests with just one Republican candidate and one Democratic candidate. Recent presidential results for each district are included. While individual contests can be subject to extraordinary circumstances that make them unreliable indicators of the electoral environment, the results of all the special elections in a cycle have a good track record of predicting November outcomes. Our special elections database has also been widely cited in the press.

Media Markets.
Media markets are an important tool for understanding how an electoral contest develops, as ad buys are usually reported by market, not district. We’ve calculated presidential election results for media markets going back decades, and for recent congressional district lines, we’ve calculated how much of each congressional district is in each media market, and how much of each media market is in each district.
Calendars.
Handy links showing when primaries and filing deadlines are by state, and when important elections are held in odd-numbered years. Because every year’s an election year!
Primaries.
List of primaries we’re keeping our eyes on, as well as turnout and cross-party interference.
Open Seat Trackers.
Another indicator of the electoral environment, this resource includes all planned and unplanned departures from the House of Representatives along with reasons, consequences, and links to document what happened. In addition, we track which seats have just one major party candidate running. The legislative district tracker keeps tabs on the thousands of state legislature seats in much the same way.
Fundraising & Spending.
Another key metric to track each cycle, fundraising can tell you which candidates are in a strong position — and which could be caught napping. Independent expenditures, meanwhile, show where national organizations think the close races are (or where big donors have a pet project).
House Vulnerability Index.
The ever-useful HVI doesn’t care if the general environment is more favorable to Democrats or Republicans. It just tells you which seats are most likely to flip, and, approximately, in what order. A stronger Democratic environment just gets you further down the list.
Race Ratings.
Our archived read of the state of the races.
Candidate & Politician Guides and Demographics.
Our candidate and congress guides compile demographic data for all officeholders and every competitive candidate in Congress, and demographic data for the districts themselves. Presidential and candidate vote shares in each district are shown as well. Includes handy name pronunciation guide with links to videos of candidates pronouncing their own names. We also periodically take a look at which seats have a congressional representative with an ethnicity that differs from the majority or plurality of their district.
State & Congressional District Demographics.
Can’t name the major cities in CA-35 off the top of your head? Jealous of the UK’s constituency names like Berwick-upon-Tweed? Well, we’ve got just the thing for you in our geographic descriptions files… although, maybe not as amusing as the UK names. That, along with numbers for race, ethnicity, ancestry, education, income, age, citizenship, religion, and urban/rural classification, can all be found in this section.

District Relationships.
What makes up a district? We have the answer! Whether in terms of counties, other districts, or old districts, our tables can illuminate the relationship.
Maps.
We love maps here at Daily Kos Elections, and we know we’re not alone. So we’ve made templates available for some of our favorites, including our non-contiguous congressional cartogram with equal area for each district, a regular congressional district map with water boundaries, and our tile map with one hexagon for every state.
