The Minnesota U.S. Senate race remains a tossup on the final weekend of the campaign, with the outcome likely to be decided by who can snatch away the most voters from third-party contender Dean Barkley.
A new Star Tribune Minnesota Poll shows DFLer Al Franken clinging to a slim lead over Republican Sen. Norm Coleman among likely voters, 42 percent to 38 percent. That's within the poll's 4.1 percentage point margin of sampling error.
Independence Party candidate Barkley, who held steady at 18 percent in the two previous Minnesota Polls, slipped three points to 15 percent.
The fluid nature of the contest is reflected in the results of a handful of polls the past week that reported results ranging from a six-point lead for Coleman to a five-point lead for Franken.
What this means is that after more than a year of exhaustive campaigning, a whopping $40 million spent and nonstop ads ranging from policy clashes to character attacks, it could be a last-minute development -- performances in tonight's final debate on Minnesota Public Radio, unusually heavy voter turnout or ongoing fallout from breaking controversies -- that determines the outcome.
In the past few days, Coleman has charged Franken with breaking the law by allegedly airing falsehoods in his ads. Meanwhile, the senator has faced questions about two lawsuits alleging that his wealthy friend transferred $75,000 to him from a Texas company through his wife's employer. Each candidate vehemently denies the respective accusations.
Both events came to light midway through the period that the poll was conducted, Wednesday through Friday.
The challenge now for Franken and Coleman is to draw the few remaining undecideds -- 4 percent of those surveyed -- and peel away enough votes from the sizable bloc commanded by Barkley, who launched his first and only TV ad last week.
