Joe Biden, the Democratic presidential candidate, will pay a visit to Minnesota next week, his campaign said Thursday, according to reports. 

The Sept. 18 visit marks Biden's first campaign stop in Minnesota during his 2020 campaign and comes on the heels of his wife, Dr. Jill Biden's visit on Wednesday.  

No other details on Biden's visit have been released. 

Biden's trip comes as a growing number of political wonks view Minnesota as a battleground state that could vote Republican for president for the first time since Richard Nixon in 1972 (the longest streak in the nation).

After narrowly losing to Hillary Clinton by 1.5% in 2016, Trump has been confident he can flip Minnesota.

As Biden continues to lead Trump among Minnesota voters (he's up by 5 points, according to a RealClearPolitics average), Trump's campaign is working to woo Minnesotans and win the state's 10 electoral votes – the president, son Donald Trump Jr., daughter Ivanka Trump and Vice President Mike Pence have made stops in Minnesota in recent weeks. 

Meanwhile, The Hill reports the campaign started running a bunch of ads in the state last week as part of his $14 million ad campaign in Minnesota.

That's different from the 2016 presidential election when neither Hillary Clinton nor Trump spent money on TV ads in Minnesota. Biden's campaign is planning to spend about $3 million in TV ads leading up to the election, The Hill notes.
