According to Ballot Access News, the Constitution Party ranks third nationally among all US political parties in registered voters, with 438,222 registered members as of October 2008, although 370,405 of those members belong to the American Independent Party in California. In 2006, Rick Jore of Montana became the first Constitution Party candidate elected to a state-level office, although the Constitution Party of Montana had disaffiliated from the national party a short time before that election. On April 26, 2008, Chuck Baldwin was nominated as that year's Constitution Party candidate for President of the United States.
Many of the Constitution Party's state affiliates appear under various names. The Michigan affiliate has kept the
U.S. Taxpayers Party name to retain ballot status. In Connecticut the affiliate
is the Concerned Citizens Party. In Nebraska the affiliate has changed its name from "The Nebraska Party" to
"The Nebraska Independent Party." Reports that the Constitution Party discussed a merger between several third
parties such as the Reform Party, Independent American Party, American Independent Party, and the America First
Party have been refuted by other accounts of the events. Nevertheless, all of the aforementioned parties except for
the Reform Party endorsed the Constitution Party's Michael Peroutka as their Presidential candidate in 2004.
