The 2012 General Election data have been updated today to reflect the final official town and county totals in Massachusetts. In addition, several states have published amended results - including New York and New Jersey. I have also added several corrections as discovered during compilation of individual county reports.

Data files available on the store page are also updated with these latest results.

With the addition of official MA county/town data, this brings to a close the official data compilation for the 2012 General Election. Further updates will consist of corrections or write-in votes discovered during precinct compilation.

2008 General Election data for President by city and town have been added for the states of Michigan, Illinois, Pennsylvania, Ohio, New Jersey, Kansas, and a partial set from Indiana. These data are not fully reconciled with official totals. However, there are a lot of good matching data for most of the counties in these states. Statewide township maps and individual county township maps (Michigan and Illinois) will be forthcoming.

The 2012 Republican Primary county and state-level data have been updated to final/official results (Utah, the last state to hold its nominating contest just certified its results last week). Some congressional district data and a number of maps are still in-process.

I have discovered that the Texas Secretary of State official election results from the 2012 Republican Primary have shorted Romney by an even 100,000 votes. This occurs in Harris County where the tally shows Romney with 11,380 votes. The official results posted on the Harris County Clerk’s web page show an official total of 111,380. A small typo shifted the results by a whopping 100,000 votes. While in this case, the election was no longer contested and even this large number of votes did not change the result, it does show how simple errors can cause very large numbers of votes to be miscounted.  I have contacted the Texas Secretary of State about this discrepancy.

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.
