I haven't verified thus news of Joe Biden stepping down from the presidential race, but the truth is that, if the incumbent president is not running for the office of the president of the United States, it indeed increases his opponent chances of winning the race this is because, any replacment of condiddate have wand will weaken their political strategy and if the opposition is strong enough, winning will be closer to them than when they are up against seating president.
I just checked the news now, and Biden is out of the race, but then we can't say this will lead to a slid winning for Trump but it indeed increases his chances at the poll, anyways Trump have alot going for him this time, and I am sure he is going to have some good traction and record in the coming ballots,
