Next Tuesday night, Republicans and Democrats hold precinct caucuses to elect delegates to this summer's party conventions. This week, Minnesota Public Radio is profiling the candidates vying for their endorsement. St Paul Mayor Norm Coleman earned himself weeks of media attention by refusing to say whether he was running for governor. His coyness on the topic generated weeks of media speculation, and jealous gubernatorial candidates in both parties grumbled that he should make up his mind. Coleman finally did earlier this month, and formally entered the race on February 15. Minnesota Public Radio's Martin Kaste has this profile of the candidate.
