Using Google maps and the presidential election results by legislative district calculated by the team at Daily Kos Elections, we've created interactive maps of those results along with the most recent legislative elections results for each state. We've compiled all of those maps into a single source you can bookmark. You'll find links to each state legislative chamber by year since 2012, and we'll keep this resource updated going forward.
For each map, districts in solid blue were carried by Barack Obama and are represented by a Democrat, while those in solid red were won by Mitt Romney and are held by a Republican. Lighter red districts voted for Obama and a Republican legislator, while those in lighter blue went for Romney and a Democratic legislator. Some states have multi-member districts; those electing a split delegation but voting for Obama are the lightest red while split delegations in Romney districts are the lightest blue.
Districts held by independents are in green, while those held by Democratic or Republican legislators who cross the floor to caucus with the other party are yellow. All vacant seats are assigned to the party that last won them. Note that the 2012 maps display only the two-party vote, but Daily Kos Elections' numbers include the totals for third-party candidates, as do the 2014 maps; however, the differences are minor. A few chambers require two separate maps to visualize their membership, as explained in the notes beneath the chart below.
Notes:
-
Independents: Independents and members of third parties are indicated as caucusing with Democrats or Republicans, if this information is available.
-
Idaho: The state House of Representatives holds two separate elections in each district.
-
New Hampshire: The state House of Representatives has a set of districts called “floterial districts” that overlap with traditional districts, in order to give certain areas additional representation.
-
Washington: As with Idaho, the state House of Representatives holds two separate elections in each district..
-
West Virginia: State Senate districts elect two members to staggered, four-year terms. Those elected in presidential cycles are denoted as "A" and those in midterms as "B."
