MILWAUKEE (AP) -- A taxpaying question that may have led one candidate to drop out of Wisconsin's U.S. Senate race isn't a factor in the other candidates' campaigns.
State documents say Oshkosh Republican Ron Johnson paid Wisconsin taxes every year from 1994 to 2008. The average amount was $55,000.
Madison developer Terrence Wall dropped out of the race last month after Johnson won the state party's endorsement. Wall's bid stalled after reports that he owed zero state income tax in nine of the past 10 years.
Johnson's GOP challenger is Dave Westlake of Watertown. Westlake paid an average of $3,800 per year in state taxes since 2000.
Democratic incumbent Sen. Russ Feingold paid an average of $7,400 per year over that same period.
Johnson's tax figures were first obtained by the liberal group One Wisconsin Now.
