Polls do not equal the political reality of the United States whatsoever. That is something one needs to understand from the first move one does when getting into geopolitics also the inner politics of the United States. Those polls are made with a sample of the population, which means the poll could be biased or inaccurate, depending on the team behind them.
Look for example what happened during the midterm elections of 2022, according to polls the Republican party was supposed to gain advantage over the Democrat party both in the Senate and in the House of Representatives, it did not happen.
So if you are new at betting and American politics, I would recommend you to be skeptical of pols and see a little bit more how betting markets react to the actions of both candidates.
