Donald Trump's surging presidential bid gets an important test in Minnesota this week, when the billionaire Republican front-runner tries to rack up a win in a state that has not yet had an up-close view of his combative campaign.
The four remaining top contenders from the two parties all have poured months of time and campaign resources into winning Minnesota's March 1 caucuses. Thousands of party faithful are expected to pack voting sites on Tuesday night with Minnesota's voting among the dozen caucuses and primaries nationally that make up this year's pivotal Super Tuesday.
On the Democratic side, both Hillary Clinton and Bernie Sanders have made multiple Minnesota stops, amassed impressive volunteer forces and taken to the TV and radio airwaves as they battled to the last minute for support. Sanders has lavished the most personal attention on Minnesota of any candidate from either party, swinging through Hibbing on Friday and Rochester on Saturday evening as he tries to peel off a badly needed win over Clinton in a state his campaign views as friendly turf.
The two main Trump alternatives for Republicans, Sens. Marco Rubio of Florida and Ted Cruz of Texas, also have campaigned in Minnesota and built teams of prominent supporters and volunteers. Trump has never visited, and his campaign made its initial organizing steps here less than a month ago.
But the energy gathering from Trump's three-state winning streak could materialize at caucus sites in this high-voter turnout state, which has previously shown an unexpected fondness for such unconventional outsider candidates as former Gov. Jesse Ventura.
"Clearly he has momentum within the court of public opinion," state Republican Party Chairman Keith Downey said of Trump. Downey thinks Trump, Rubio and Cruz all have a shot at winning Minnesota.
With hundreds of delegates at stake on Super Tuesday, this year's wild, occasionally surreal presidential race is kicking into high gear. While Minnesota's delegate haul is relatively small, Democratic and GOP candidates alike worked to win here.
"Right now it's just too tight to tell," state DFL Party Chair Ken Martin said of Clinton vs. Sanders. In his view, Clinton has assembled a superior get-out-the-vote operation but Sanders has unleashed more "organic energy." Martin expects good turnout, but doesn't think it will exceed the 2008 record, when Clinton finished a distant second to Sen. Barack Obama.
