(Madison, WI) — No Wisconsin incumbents tasted defeat when running for national positions in Tuesday’s primary elections. Four of the state’s eight members of the U-S House of Representatives delegation ran unopposed. The other four prevailed easily. Democrat Mandela Barnes won the right to oppose Republican incumbent U-S Senator Ron Johnson in the November general election. Republican Tim Michels edged former Lieutenant Governor Rebecca Kleefisch by about 30-thousand votes in the primary that determined who will meet Democratic Governor Tony Evers in the fall.
