MILWAUKEE (AP) – Eager voters lined up even before the polls opened at 7 a.m. in Wisconsin on this Election Day.  More than 300 people were in line when a south side Milwaukee polling place opened Tuesday morning. About 50 were in line at a St. Francis polling location.  It could be an indication of what’s expected to be a busy day for poll workers in the battleground state of Wisconsin.  The Government Accountability Board has predicted nearly 70 percent of eligible voters will cast a ballot in the Badger State.   The big race is for president and the state’s coveted 10 electoral votes. Wisconsin voters also will choose a new U.S. senator, a House representative and state legislators.  Wisconsin voters will deal with a wintry mix of rain and snow. An inch or more of snow is forecast for northern Wisconsin, with cold rain to the south.
