WASHINGTON - In Minnesota's Fifth Congressional District, Republican candidate Chris Fields wants to make this fall's election a referendum on race.
Fields is black. So is his opponent, Democratic U.S. Rep. Keith Ellison, who is seeking a fourth term.
Fields claims Ellison has failed black constituents in what is the most ethnically diverse district in the state, a claim Ellison rejects.
Fields' approach is part of a Republican strategy being used in congressional districts across the country, from Oakland, Calif., to Memphis: Challenge black incumbents on racial issues by running black candidates against them.
"It would be impossible for a white candidate to make the same kind of appeal," said University of Wisconsin political science Prof. David Canon. "The Republicans have increasingly done that over the last couple of election cycles."
At least 30 black Republican candidates ran for Congress in 2010, the most in more than a century, and at least half that many are on ballots in 2012. Not all the candidates are challenging black incumbents, but it's a common theme.
Party operatives hope the black candidates can slowly chip away at party loyalty in Democratic-leaning districts like Minnesota's Fifth, Canon said, where almost 30 percent of the district's residents are non-white.
In an online video, Fields tells viewers: "Vote for this black guy [himself], not that one," pointing to a smaller picture of Ellison. Another online video questions Ellison's commitment to lowering black unemployment.
