Chad Lee, the young Mount Horeb resident who is challenging six-term incumbent U.S. Rep. Tammy Baldwin, D-Madison, in the Nov. 2 election, said in a debate Sunday night his opponent is a failure. Lee, 27, who owns and operates a residential and commercial cleaning business, told the 110 people who filled a room in UW-Madison?s Grainger Hall, that he has “no lifelong dream to be a politician, nor do I have a dream to be a lifelong politician.” The debate was a Global Affairs Forum organized by the United Nations Association-Dane County and nine other civic groups.
