Yes, we have U.S. House race data! Actually, we have posted charts for House races for some time, but on Friday we finally put up our revised House map (it's accessible via the "map chooser" pull down from any of the large maps on the site) and added that page to our main menu.
Readers should know that public polling data for U.S. House races tends to be more rare. In 2006, we scoured various sources for poll in House races and ultimately found polls in just 94 of the 435 districts. This time, we created a map with labels for the 111 districts rated as competitive or potentially competitive by our colleagues at the Cook Political Report. So far, we have logged in poll results for 60 districts, with another dozen or so on the way this week.
A note of explanation about the map and House scoreboard: Where we have poll data, we classify the race based on the polling data using the same criteria as for the statewide races. Where we have no polls at all, we assume no change in party status.
We assume there are U.S. House surveys out in the public domain that we no nothing about. So if you know of a poll in a U.S. House race that's not listed here, please email us (questions at pollster dot com) with the details. Thank you!
