In 2018 and 2020, the Democrats clearly and permanently solved their voter turn out problem.
The Democrats have had a completely legal national majority for at least two decades. They can win the White House without voter fraud, and they can get small majorities in both houses of Congress - if they get all their legal voters to the polls.
The only reason we won in 2016 is because White Conservatives always have the highest turn out, because Trump was a completely unique candidate, and because polling in WI, MI, and PA was off by a few percentage points in each state.
It does not matter how badly the Democrats govern.
Only a small percentage of their usual voters will even think about switching to the GOP.
LOL Republicans nearly won the house in a bad year with significant chanting with a D+6 generic polling advantage. What do you think happens when its R+10 like we’re seeing now (Hint 2010), especially with high levels of inflation which is going to get worse this year - not better.
