'One prime example of voter fraud was Tim Johnson's election in 2002. A woman was caught red handed gathering voter registrations and falsifying absentee votes from indian reservations in his support.
There was no subsequent investigation to see if it was wide-spread or democratic party sanctioned. Johnson would have lost without her "support". I'd note that the voter fraud aspect is not treated in his wikipedia post(though the indian reservation angle is obtusely disclosed).
Quote:
Johnson narrowly defeated three-term Senator Larry Pressler (R) in the 1996 U.S. Senate election, making him the only Senate candidate that year to defeat an incumbent in a general election, in a year that saw thirteen open seats. In 2002, he defeated his successor in the at-large House seat, U.S. Representative John Thune (R), by 524 votes to win re-election. Johnson's re-election race was widely seen as a proxy battle between President George W. Bush, who had carried South Dakota comfortably in 2000, and the state's senior Senator and Johnson's fellow Democrat, Senate Majority Leader Tom Daschle, who was subsequently up for re-election in 2004 and lost to Thune. In his 2002 election, Johnson won ninety-four percent of the vote among the Oglala Sioux, South Dakota's biggest tribe.[20]
