MADISON, Wis. – America's three-ring presidential circus is camped out for the moment in Wisconsin, a state all too familiar with political upheaval and a potential general election battleground in this wild and often surprising race.
The Wisconsin primary on Tuesday lands at a relative lull in the calendar of state presidential contests, leaving ample time for the Republican and Democratic contenders to campaign across Minnesota's eastern neighbor. All five stumped throughout Wisconsin in the past week, flooding the airwaves with commercials and plotting last-minute stops.
"If we win in Wisconsin, it's pretty much over," Republican front-runner Donald Trump, currently trailing in polls here to Texas Sen. Ted Cruz, said last week at a rally in Janesville.
For Republicans trying to derail Trump's candidacy, Wisconsin has emerged as a last-ditch bulwark of their strategy.
It is also the latest front in Democratic front-runner Hillary Clinton's attempts to close down Vermont Sen. Bernie Sanders, and polls show a tight race with a likely split between the state's two largest cities.
"Madison is absolutely home base for a candidate like Sanders, and the city of Milwaukee is made for Hillary Clinton," said Joe Zepecki, a Wisconsin Democratic strategist.
Since first electing Republican Gov. Scott Walker in 2010, Wisconsin has emerged as an emblem of the bitter divisions that now define America's political discourse.
Walker and a Republican-controlled Legislature pushed state policy far to the right of center by drastically curbing union power (triggering massive statehouse protests in response), lowering taxes while cutting state aid for public schools and universities, and enacting strict voter ID laws.
