This afternoon delegates to the state DFL convention will enthusiastically endorse Minnesota Senator Paul Wellstone's bid for a third term. Wellstone is expected to deliver a trademark passionate speech outlining his sharp ideological contrast to the Republican agenda. Wellstone will not formally kick off his campaign until later this month even though the contest with Republican challenger Norm Coleman is well underway. Minnesota Public Radio's Mark Zdechlik prepared this report on Wellstone's Senate career and why the Senator is pursuing a third term he repeatedly pledged NOT to seek.
