The six-month election recount that turned former "Saturday Night Live" comedian Al Franken into a U.S. senator may have been decided by convicted felons who voted illegally in Minnesota's Twin Cities. That's the finding of an 18-month study conducted by Minnesota Majority, a conservative watchdog group, which found that at least 341 convicted felons in largely Democratic Minneapolis-St. Paul voted illegally in the 2008 Senate race between Franken, a Democrat, and his Republican opponent, then-incumbent Sen. Norm Coleman. The final recount vote in the race, determined six months after Election Day, showed Franken beat Coleman by 312 votes -- fewer votes than the number of felons whose illegal ballots were counted, according to Minnesota Majority's newly released study, which matched publicly available conviction lists with voting records. Furthermore, the report charges that efforts to get state and federal authorities to act on its findings have been "stonewalled." "We aren't trying to change the result of the last election. That legally can't be done," said Dan McGrath, Minnesota Majority's executive director. "We are just trying to make sure the integrity of the next election isn't compromised."
