Is there any accurate data?

I would like to see the results of honest polling in each of the swing states that decided the 2020 election. You know, the ones that have been in question all along.

i’d like to know the voter turn out for Democrats and Republicans.

Then i’d love to know how many Democrats voted Trump/ how many Republicans voted Biden, especially the latter.

How many Republicans voted Republican down ballot and Biden for President?

How many Republicans voted Trump in 2016 but switched to Biden in 2020?

How many Democrats voted Hillary in 2016 but switched to Trump in 2020?

How many people who voted in 2016 decided to sit it out in 2020?

Just curious. Is there any trustworthy data out there?
