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 special gubernatorial election in West Virginia has been added to the atlas polls and predictions scripts.  Note that this election is not held on November 8th, like the general elections in Kentucky and Mississippi, rather it occurs on October 4th.  The prediction for West Virginia will close earlier than election day (October 4), similar to Louisiana, where the prediction will close on the open primary day of October 22.

The Electoral College Calculator has been updated for 2012 - incorporating the just-released apportionment figures from the U.S. Census Bureau. The new Electoral Vote figures for each state reflect the changes in population growth across the country as measured in the 2010 Census and are the basis for the 2012 Presidential Election contest.

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″.

Yesterday, the Atlas operating system software and core services were upgraded. This included the core OS, Apache, MySQL, and PHP. Please submit a bug if you happen to find that any of the site features were broken by this upgrade. Many thanks and enjoy!

The Atlas Server was replaced today with a new motherboard, faster processor, and more memory. Enjoy the improved performance!

Election data and maps from the 2006 General Election for U.S. Senate and Governor for most states have been uploaded to the site. A few states remain to release their official data, including my home state of Massachusetts. The expectation is for these data to be available within the next couple of weeks. The detailed county and town-level spreadsheets have also been updated with the most recently-available information.

Preliminary, unofficial election results (data and maps) for the 2006 Senate and Governor’s races are on-line. These data will be updated as election agencies across the country finalize and post official tallies. A final official compilation of data for all states is expected in early January. Population data for 2006 will be added when these data are released by the Census Bureau. Preliminary detailed spreadsheet files for these contests are available at the store. As always, once purchased, updates to spreadsheets are free.

The site has recently added state-level (and some county-level) data for the Presidential Elections of 1876, 1880, 1884, and 1888 to the database. The total figures for some states have changed slightly from the original html files due to differing figures between the primary sources referenced and the source used to create the original html tables (see What was the Real Popular Vote? entry for some additional information with regard to why popular vote figures for older elections are so variable.). Work continues to add data from older elections (state-level data, county-level data, county-boundary accuracy and image-mapping, etc.).

The new Wiki in addition to the continued growth of the Atlas Forum had caused the server to bog down on occasion. This performance issue has been addressed today with a memory upgrade (1.5GB from 750MB). Please continue to enjoy the site!
