Bidens MI lead over Trump was 4.2. Harris's MI lead over Trump is 0.7 and Trump is ahead in 3 of the last 4 polls.
Let's take a look at the most recent Michigan polls. https://projects.fivethirtyeight.com/polls/president-general/2024/michigan/
Let's do so Sir. In 2020 538 had Biden +7.9 in MI.RCP had Biden + 4.2 in MI. RCP was far closer to the actual result of 2.8 than 538 who had Biden a ridiculous 8 points ahead.
RCP doesn't include all the garbage left wing polls that 538 does.Thats why RCP was only off in MI in 2020 by 1.4 points while 538 was off by 5.1 points.
