The large queues to vote will definitely be in Trumps favour. Trump supporters love him and will be willing to queue. Biden voters don't particularly like him but prefer him to Trump so I can't see them waiting several hours to vote in person.
There are many reasons people queue to vote. Remember the ballots contain far more questions than just 'Who do you want to be president.'
People will queue to vote for/against Trump/Biden and they''ll queue to vote for all the other candidates and issues on the ticket.
In my state, they're voting on Susan Collins (AKA they're voting for control of the Senate), they're voting on their representative to Congress (control of the House), on their state representatives and senators, on their local town councils and school boards, on town/school budgets and bonds.
They're voting on rent control ordinances, minimum wage ordinances, AirBNB regulation rules, changes in zoning ordinances... They were going to vote on whether the electricity company is allowed to carve a huge swathe through the empty forests in the west of the state, but the question was taken off the ballot at the last minute.
People really REALLY hate the electricity company. They would've waited for days to vote against them, if they had to.
One year there was a vote on whether bear baiting should be made illegal.
Another year there was a referendum on gay marriage. (It passed btw. First state to make gay marriage legal via popular vote.)
When you see people in the US queueing to vote, they're voting for so many more things than just what you hear about in the national news.
A friend is volunteering in Orlando, supporting people who are waiting in line for hours to vote. She brings them drinks and food from the food trucks (which are donating everything for free). She gets them anything else they need. She thanks them for turning up to vote and if necessary she drives them home afterwards.
