So you're saying Trump may have won Michigan by an even larger margin than what he got?
If the recount had been allowed to go through and showed this to be the case, you just inadvertently gave voter ID laws a legitimate premise.
Also on topic. People need to stop blaming this all on Hillary, that's how Trumo not only wins all the same states as this year in 2020, but also adds Minnesota and Maine, although Minnesota will turn red soonish anyways, it's been trending that way for some time.
Honestly if voters find Trump to be even ok, 2020 could be a landslide no matter what Democrats do, it's quite hard to defeat an incumbent with even decent approval ratings, and Trump was able to win with horrible numbers.
2022 midterms and 2024 presidential election will be the true test as improving the Senate in 2018 is a pipe dream due to the shear math of it, only hope is to prevent a Republican supermajority.
