NCPP Analysis of Final 2012 Pre-Election Polls
The National Council on Public Polls (NCPP) has released its analysis of final national and statewide pre-election polls for the 2012 elections. The analysis published in December 2012 has been updated with the final official vote totals released by the states by early January 2013. There were small changes in some summary numbers as a result of the comparison with final vote tallies.
