In this crucial 'blue wall' battleground, Trump and Harris hold dueling final rallies.

In Milwaukee, Wisconsin, on Friday night, Vice President Kamala Harris and former President Trump will hold competing rallies at the same time, only a few miles apart in the city's largest battleground.

In the final stretch before Election Day, both Democratic and Republican presidential candidates visit Wisconsin, where recent polls suggest a tight race with a margin of error.

According to University of Wisconsin-Milwaukee professor emeritus Mordecai Lee, as of this weekend, predicting the winner is a coin toss, as it's that close, he told Planet Chronicle.

In two days, Harris and Trump will hold competing rallies in the same city, with Harris stopping in Madison and Trump in Green Bay.

During the Republican National Convention in July, Trump accepted his party's presidential nomination at Milwaukee's Fiserv Forum. Meanwhile, Harris will hold a get-out-the-vote rally a few miles away at the Wisconsin State Fair Park Exposition Center.

The president will be arriving in Wisconsin from Michigan, another key battleground, where he held campaign events earlier on Friday.

Cardi B will make remarks at Harris' Milwaukee rally, which is her third Wisconsin event of the day. She previously stopped by a union hall in Janesville during the afternoon.

Harris replied, "Not yet! Four days," as a group of union members began shouting "Madam President."

The vice president contended that "Donald Trump is not pro-labor."

The vice president went to Appleton to give a speech at a school rally.

The vice presidential nominees of the Democratic and Republican Parties, Minnesota Gov. Tim Walz and Sen. JD Vance of Ohio, have both visited Wisconsin. Additionally, major surrogates, including former Presidents Obama and Clinton, have arrived in the state to support Harris.

In the weeks leading up to Election Day, both campaigns and their affiliated committees and super PACs have bombarded Wisconsin airwaves with TV advertisements.

The "blue wall" in the Rust Belt region comprises of Wisconsin, Michigan, and Pennsylvania, which are all Democratic states.

For a quarter-century, Democrats consistently won all three states until Trump narrowly captured them in the 2016 election, defeating Democratic nominee Hillary Clinton to become President of the United States.

In 2020, President Biden won all three states by very narrow margins, with Wisconsin being the closest by just over 20,000 votes out of over 3.2 million cast.

In Wisconsin, the outcome of the race may depend on voter turnout.

The Harris campaign emphasizes that they have 50 offices spread across 43 counties in the state and 250 full-time staff members working on the ground.

They highlight that they have knocked on over 1.5 million doors in the fight for Wisconsin's 10 electoral votes.

The Packers and Vikings rivalry was used by the Trump campaign to criticize the vice president.

According to Karoline Leavitt, the Trump campaign national press secretary, Kamala Harris lacks knowledge about Wisconsin, as she selected a Vikings fan as her running mate. Wisconsin voters are already showing support for President Trump, with his lead in the polls, early vote turnout, and big endorsements from hometown favorites such as Hall of Famer Brett Favre and Wisconsin's Former Governor Tommy Thompson.

Nearly five decades of involvement in Wisconsin politics has given Lee ample reason to highlight the state's current attention.

He stated, "We believe we will choose the next president."
