Minnesota's Independence Party candidates made a strong showing in Tuesday's election, by third-party standards. But their double-digit vote totals in several hard-fought races are reviving questions about the role the party is playing.
Does the IP embody a developing political movement, seeking to provide an alternative to an increasingly dysfunctional two-party establishment? Or is the party mainly a so-called spoiler -- seldom able to mount competitive candidacies while frequently doing more damage to DFLers than to Republicans.
Since its founding in the early 1990s, the IP has managed to win exactly one high-profile race, the election of Gov. Jesse Ventura a decade ago.
"They're looking more and more like spoilers at this point, pulling swing voters away from the Democrats," said David Schultz, who teaches political science at Hamline University in St. Paul. "They certainly aren't getting enough votes to win, but the IP has been capturing the swing votes."
Nowhere was the impact of the party more pronounced than in the still-knotted U.S. Senate race. With only hundreds of votes out of nearly 3 million cast separating Republican incumbent Norm Coleman and Democrat Al Franken, Independence standard-bearer Dean Barkley got more than 437,000 votes.
And, according to an exit poll conducted Tuesday, if Barkley hadn't been running, Franken would have netted more than 20,000 additional votes.
"The Democrats still outnumber the Republicans, but they aren't at 50 percent," Schultz said. "So if the swing votes go to the Republicans, it almost equalizes the campaign even if the Democrats hold onto their base."
Barkley, one of the party's architects and mastermind behind Ventura's victory, waves away the argument that his candidacy swayed the election one way or another.
