Wisconsin’s primary is alone on Tuesday’s primary calendar, and that means candidates have been focusing their campaigns almost entirely on the Badger State over the past several days.

The latest poll shows Vermont Senator Bernie Sanders with an edge over Hillary Clinton, while Texas Senator Ted Cruz is widening his lead over Donald Trump.

One key to the Republican vote will be winning the suburban counties around the state’s largest city of Milwaukee. Those suburbs are home to many of the state’s most politically-active Republicans.
