The preliminary data file for the 2012 Republican Primary contests has been posted to the store page. Many contests have certified official data, but data from several states are currently unofficial. Data by congressional district is available for a few states - note that redistricting has slowed this process. Several states tabulated results by congressional district, but did so for the old 2002-2010 boundaries - these data are not included as they are irrelevant to the delegate allocation. Compilation continues and the file will be updated periodically. All updates of purchased files may be downloaded for free.

The 2010 Election Data has been updated - all states are now official. The last state to make public its detailed data is Massachusetts - where the official data by county is published in a the paper book called “Public Document #43 Massachusetts Election Statistics” - the document has just been released.

The 2010 Election Data has been updated - most states are now official. Exceptions are late results by county for Governor in Maine and Kansas as well as the Alaska Senate. In addition, several states do not certify their results for Governor until January (these include Texas, Tennessee, and Iowa). Massachusetts official data by county will not be available until some time in the spring after they publish the paper copy of “Public Document #43″.

The first update to the 2010 election results on the site as well as the data files are now available. Official results have been posted for a few states that certify their elections within a week. Other states have been updated to reflect continuing accumulation of absentee ballots.

Preliminary 2010 General Election data spreadsheets by county for U.S. Senate and Governor are now available for purchase on the store page. These data are incomplete and may contain inaccuracies at this stage. The files will continue to be updated as official results are certified - the last state to do so is California on December 8. As always, updates for purchased files are free.

Another exciting election has now passed - after a long night and very long day of compiling and uploading results, the web-based data, maps, and charts for the 2010 General Election for U.S. Senate and Governor are mostly uploaded. There are a number of states where county-level data are not yet available from their respective election agencies. Not all states are at 100% reporting level as yet and will be updated in the next few days. An incomplete, preliminary version of the data files will likely be available on the store page tomorrow.

The Atlas results database has been upgraded to support the event in which two U.S. Senate races occur in the same year from the same state. The term “class” has been added to distinguish between the elections. There are three U.S. Senate classes that alternate every two years - repeating every six. 2010 is a class 3 election. There also happen to be three Special Elections that are also taking place on November 2, 2010 - Delaware (Class 2), West Virginia (Class 1), and New York (Class 1). Delaware and West Virginia do not have a Class 3 Senate seat, and therefore have only one contest on November 2. New York, however, does have a Class 3 Senate seat and has two Senate contests on Nov 2. To support this, I’ve upgraded all general election contests from 1990 through 2010 - and all the past special two-senate-from-one-state contests not previously included in the results menus are now available. These include 1992 CA & ND, 1994 TN, 1996 KS, 2008 MS & WY and 2010 NY.

The map at the right shows a small version of the statewide results in Washington of the 2008 General Election for President by precinct (Obama in Red, McCain in Blue). This was made possible because the Washington Secretary of State has posted all the precinct-level GIS shape files. Most of the shape files line up with the county precinct data (although there are a number of discrepancies). The map link to the right brings you to the forum topic discussion on the 2008 Presidential Results by Precinct in Washington. The maps provide a very detailed geographic breakdown of the results, clearly showing the urban-rural split that has developed between the Republican and Democratic regions of support. Additional tweaking of the map is planned to incorporate the closest match to precinct boundaries used in the 2008 General Election for several counties.

The preliminary (unofficial) results of the 2010 Massachusetts Special Senate Election are available. In a surprise, Republican candidate Scott Brown defeated Democratic candidate Martha Coakley 52% to 47%. This result is actually very similar to the 2002 Gubernatorial Election Result where Mitt Romney defeated Shannon O’Brien by 5 percentage points (50% - 45%). Also, interestingly, the voter turnout for the snowy January 19 Special Election actually exceeded the turnout in both the 2002 and 2006 General Elections (preliminary figures show 2,249,026 votes in the special election vs. 2,194,179 votes in the 2002 General Election and 2,219,779 votes in the 2006 General Election).

The 2008 data files for US President, US Senate, US House of Representatives, and Governors have been updated - these mostly include updates to Massachusetts - which only recently released “Public Document #43 - Massachusetts Election Statistics” - the only official data to the city and town level.  The files also include several corrections to the official data discovered during compilation of precinct returns. These files are available for immediate download on your myatlas page (for previously purchased files.

A new 2008 voter registration and turnout file is also now available on the store page.
