In an effort to challenge John McCain, the Democratic National Committee launched a new Web site Monday called "McCainpedia" with the aim of bringing voters the "raw facts and research" of McCain's record.

The "online encyclopedia" is the latest Internet tool used by the DNC to engage voters in the election process, spokesman Dag Vega said in a press release issued Monday.

The multimedia Web site, which lists the Arizona senator's positions on the issues, allows viewers to watch, download and use video taken by Democratic trackers of McCain on the campaign trail.

It posts rebuttals to McCain's views on a host of subjects ranging from the economy to same-sex marriage. Of McCain's position on the Iraq war, the site criticizes him for "spouting rosy and empty rhetoric" and missing 22 votes on the war while traveling around the country campaigning in the general election.

According to The Washington Post Votes Database, McCain has missed 346 votes this Congress. Democrat Barack Obama has missed 241 votes and Hillary Clinton has been absent for 183 votes during the same period.
