In five Wisconsin congressional seats, incumbents easily prevailed over challengers Tuesday. None of the races were considered close in advance of Election Day, and all of them were called by the Associated Press before 10 p.m.

In the 2nd Congressional District, Democratic incumbent Mark Pocan defeated Republican Erik Olsen by a margin of more than 2 to 1, with 87% of the vote counted. The district is centered on Madison and covers south central Wisconsin.

In Milwaukee’s 4th District, Democratic incumbent Gwen Moore easily bested two challengers, Republican Tim Rogers and Independent Robert Raymond.

In the 5th District, covering suburban and rural communities west of Milwaukee, Republican incumbent Scott Fitzgerald sailed to a third term, defeating Democrat Ben Steinhoff. With nearly 80% of ballots counted, Fitzgerald had almost 65% of the vote while Steinhoff had just under 36%.

In the 6th District, which extends west from the lower Fox Valley, Republican incumbent Glenn Grothman had a 2-to-1 lead over Democrat John Zarbano.

In the 7th District, covering northwest Wisconsin, Republican incumbent Tom Tiffany easily defeated Democratic challenger Kyle Kilbourn by a margin of about 2-to-1 with half the ballots counted.
