WASHINGTON – Voters in Wisconsin will select candidates on Tuesday who will compete in some of the fall’s most closely watched races.

Republicans will choose a challenger to run against U.S. Sen. Tammy Baldwin, who is seeking a third term. There are also primaries in two U.S. House districts that could be important for control of Congress.

Voters are choosing candidates for the Republican-controlled state legislature, which will probably be reshaped in November after Democratic Gov. Tony Evers signed new legislative maps into law earlier this year. Almost two-thirds of the seats in the 99-member Assembly are open.
