MINNEAPOLIS — Voters in Minnesota are deciding whether to make President Donald Trump the first Republican to carry the state since Richard Nixon in 1972 — or to hold to their usual line and back former Democratic Vice President Joe Biden.

Other top races on Tuesday’s ballot include a U.S. Senate race, all eight congressional seats and a struggle for control of the Minnesota Legislature.

A record number of Minnesotans voted early to avoid potential long lines on Election Day and the threat of the coronavirus. The state told voters it would count absentee ballots that came in up to one week beyond Election Day as long as they were postmarked by Tuesday. But a court ruling last week requiring that those ballots be segregated cast doubt on whether late-arriving votes would count. The ruling further raised the possibility that some race outcomes won’t be known for days.

A look at races in play in Minnesota:

PRESIDENT

Rarely has Minnesota gotten so much attention in a presidential race. Trump set a goal of winning the state after coming within 1.5 points in 2016. Trump came back to the state for several rallies in greater Minnesota cities in hopes of firing up his base enough to put him over the top this time.

Biden campaigned in Minnesota twice this fall, a visit to Duluth on the same day that Trump rallied in Bemidji and an event in St. Paul on Friday just before Trump visited Rochester. The dueling visits highlighted how Minnesota has been in play this cycle. Republican strength has been growing in recent years across much of rural Minnesota and on the once reliably Democratic Iron Range.

SENATE

Democratic U.S. Sen. Tina Smith is facing voters for the second time in as many years after winning a special election in 2018 to fill out the term of U.S. Sen. Al Franken. She has worked to build an image as a workhorse who reaches across party lines.

Republicans put up former U.S. Rep. Jason Lewis, who was well known from his days as a conservative talk radio host and a single term in the House. He stressed his support for Trump, including their shared opposition to pandemic restrictions and a common message that they would be better for “law and order” than Democrats. Trump rewarded Lewis’ loyalty with public praise.

HOUSE

Democratic U.S. Rep. Collin Peterson, a national figure as chairman of the House Agriculture Committee, asked voters in western Minnesota’s 7th District to send him back to Washington for a 16th term. He faced his most serious challenge in decades, from Republican former state Sen. Michelle Fischbach, in one of the GOP’s best pickup opportunities across the country.

There’s also a close race in southern Minnesota’s 1st District, where freshman GOP Rep. Jim Hagedorn is trying to fight off Democratic Iraq war vet Dan Feehan in a bitter rematch of their close 2018 race. And Minnesota’s 2nd District race, for the seat representing southern suburbs, was scrambled by the death of a third-party candidate. Democratic Rep. Angie Craig went to court to block having the election delayed until February, which might have put her at a turnout disadvantage against Republican and former Marine Tyler Kistner.

LEGISLATURE

All 201 legislative seats are up for election this year, and the GOP is defending a three-vote majority in the Senate. If Democrats take the Senate and keep their comfortable House majority, they’ll control how Minnesota deals with a projected $4.7 billion budget deficit and the redrawing of state and congressional district maps. The redistricting stakes are high. Minnesota is on the bubble for losing a congressional seat after new census figures come out.

SUPREME COURT

Associate Justice Paul Thissen, a former speaker of the Minnesota House, is facing voters for the first time since his appointment in 2018. Challenging him is Michelle MacDonald, a controversial family law attorney who is making her fourth bid for a seat on a court and is facing potential disciplinary sanctions for a second time.
