It's Super Tuesday in Minnesota and the polls are open

Minnesotans will head to the polls Tuesday and join voters in 14 other states holding presidential primaries to award the largest number of delegates of the campaign season so far. Both the Republican and Democratic parties will dole out more than one-third of the total number of delegates that will nominate their eventual standard-bearer on Super Tuesday.

Democrats are also holding a presidential primary in American Samoa. In the North Star State, the Legal Marijuana Now party will host a nominating contest featuring five candidates. Polls opened at 7 a.m. in Minnesota, and they close at 8 p.m.

Both President Joe Biden and former President Donald Trump have so far won every statewide contest for the Democratic and Republican nominations, respectively.

But Biden has been plagued by a dearth of enthusiasm and a campaign criticizing his administration's response to the war in Gaza. A coalition of progressive activists is urging Democratic Farm Labor party voters to choose "uncommitted" on their ballots to press the White House on a ceasefire agreement in the region. U.S. Rep. Dean Phillips has also launched a long-shot campaign to unseat the president to mixed reactions in Minnesota and beyond. In Michigan, Phillips trailed the "uncommitted" vote.

Trump, who faces 91 criminal counts in four jurisdictions, has glided through every state primary so far. But voters in Washington, D.C., awarded their 19 delegates to former U.N. Ambassador Nikki Haley, the only presidential hopeful for a major party who has campaigned in Minnesota so far.
