The Research 2000 Massachusetts Poll was conducted for three organizations -- the Progressive Change Campaign Committee, Democracy for America, and MoveOn.org -- on Tuesday, January 19, 2010 after polls closed in the special election for Senate.

500 Obama voters who did NOT vote in the special election were asked one set of questions. 500 Obama voters who DID vote -- and voted for Republican Scott Brown -- were asked another set of questions. Each has a margin of error of 4.5%.

2774 Obama voters from 2008 who voted Tuesday were reached -- of which 2274 (82%) voted for Democrat Martha Coakley and 500 (18%) voted against her.

(Research 2000 also does polling for the St. Louis Post-Dispatch, Lexington Herald-Leader, Fort Wayne News Sentinel, South Bend Tribune, and Reno Gazette-Journal, and dozens of other media outlets. They did a Virginia 2009 post-election poll of Obama voters for the PCCC, which is located here. )
