Research 2000 was a U.S. opinion polling and marketing research company based in Olney, Maryland. It began doing research on upcoming elections in 1999 after its President, Del Ali, moved on from Mason-Dixon Political Media Research. Research 2000 clients have included KCCI-TV in Des Moines, Iowa;, WCAX-TV in Burlington, Vermont; WISC-TV in Madison, Wisconsin; WKYT-TV in Lexington, Kentucky; Lee Enterprises, the Concord Monitor, The Florida Times-Union, WSBT-TV/WISH-TV/WANE-TV in Indiana, the St. Louis Post-Dispatch, the Bergen Record, the Reno Gazette-Journal, and the political blog Daily Kos.
During the 2008 U.S. elections, Research 2000 was contracted by the website Daily Kos to conduct nonpartisan polling of various races, including presidential, senate and gubernatorial races. This partnership was slated to continue into the 2010 U.S. elections, but Daily Kos terminated the relationship in early June 2010, citing poor performance.
In June 2010, three independent amateur statisticians (Mark Grebner, Michael Weissman, and Jonathan Weissman) began investigating Research 2000's numbers and suspected that they had been fabricated. They were concerned enough to contact Daily Kos founder Markos Moulitsas with their suspicions. On June 29, Daily Kos released the findings of that investigation, which concluded Research 2000's data showed extreme statistical anomalies inconsistent with random polling. In a statement of his own accompanying the results, Moulitsas renounced all of the work Research 2000 had done for Daily Kos and also announced that Daily Kos intended to sue the polling firm for fraud. The suit was filed on June 30, 2010 in the U.S. District Court, Northern District of California.
