With the United States’ Nov. 3 election fast approaching, President Donald Trump and former Vice President Joe Biden are vying for wins in eight of the US most coveted election states: Pennsylvania, Florida, Arizona, Ohio, Wisconsin, Michigan, North Carolina, and Iowa.

Biden is polling higher than Trump in seven of the eight states. The President maintains a slight lead in Ohio.

While many Americans are weary of a heavy reliance on polling numbers, given that Trump tailed Hillary Clinton in nearly every major poll in the 2016 election, there are a few key differences in electoral polling since the last election.

For one, there is a higher margin for a Biden win than there was a Clinton win. The models have changed. Polls in 2020 do not look to correlate a win in one swing state to a win in another swing state, like they did in 2016.

There’s also the fact that, in 2016, voting for Trump was something of a taboo for American voters. People didn’t disclose to public opinion polls that they would be voting for him, but showed up at the polls to vote red anyway.

That’s no longer the case in 2020, where Trump voters are much louder and prouder than in 2016, making national polls much more predictable and stable. But Biden also pushed hard for wins in swing states like Michigan and Wisconsin just in case, which Clinton failed to do in 2016.

The presidential race is still just that- a race. Swing state voters could still show up for Trump at the polls. For many though, the fear is if they don’t. Trump has refused to promise a peaceful transfer of power, and stores like Walmart have considered taking their guns off the store floor in fear of civil unrest.

“We have seen some isolated civil unrest and as we have done on several occasions over the last few years, we have moved our firearms and ammunition off the sales floor as a precaution for the safety of our associates and customers,” a spokesman for Walmart said in a statement.

The chain seems to have reversed its decision Friday, but its sentiment remains for many who are looking to the Nov. 3 election with mixed emotion.
