Washington, Nov 2 : With the election just days away, campaign signs for both Democratic presidential candidate Kamala Harris and Republican candidate Donald Trump are seen side by side along a main road in Door County, northeastern Wisconsin.

The east north central US state is one of the seven key swing states that could determine the outcome of this year's US presidential election, and it is also one of the three Rust Belt "Blue Wall" states that Democrats are eager to defend.

With a population of approximately 30,000, Door County's voting decisions aligned with the national outcome in the last seven presidential elections.

In 2016, Trump won Door County by more than 500 votes, while in 2020, Biden won here by less than 300 votes, making it a "super swing county" in a key swing state.

The southern part of the county is characterised by farmland and the central area is dotted with small towns, while the northern section boasts numerous attractions near Lake Michigan. The region has a strong foundation in agriculture and manufacturing, notably shipbuilding, as well as a thriving tourism and catering sector.

With a diverse population, voters from different backgrounds hold widely divergent views on issues such as the economy, immigration, and abortion rights.

At a polling station in Sturgeon Bay, a city in the county's central area, Democratic voter Jean Cookle, who worked in the education field, told Xinhua that she has a neighbour just two houses away who supports a different candidate, and they never discuss politics.

Paul, a 38-year-old landscape photographer who identifies himself as a "moderate," has already made his choice to vote for Harris, while his parents are staunch Republicans for religious and cultural reasons. "We try to be courteous and respectful. Since 2016 you either have to be or you're going to lose some family and friends," he said.

On economic issues, Republican voters are more likely to believe that the Biden-Harris administration's policies have caused inflation and that the economy was better during Trump's presidency.

In contrast, Democratic voters argue that the fiscal stimulus from the Trump administration also contributed to surging inflation, along with other factors, and that the current administration has successfully reduced inflation.

Republican voter Austin Vandertie is a six-generation small farm owner who raises 40 dairy cows and also grows soybeans and corn. The 25-year-old told Xinhua that his main concern in this election is inflation, as it has driven up the costs of feed and fertilizer, "basically everything that it takes for me to make a good product."
