We'll be seeing its hints in 2022 and it will be full bore in 2024. If the holders of the old-guard strategies (McCain 2008/ Biden 2020 style campaigns) want to not get trounced in 2024, they need to make a substantial difference in peoples lives to win that election. Otherwise, 'Trumpian' style campaigns will become the norm, as they'll be show to be more effective at winning elections.
Might actually be more riding on 2022/ 2024 than 2016. 2016 proved it possible; these next elections will decide if its reproducible.
Wouldnt that be good for this particular measure given the scores reached 'new recorded high's in his presidency.
The US economy now has a modest, persistent labor deficit due to declining demographics (population growth is largely flat or negative for whites, blacks, hispanics). If you cut immigration much at this point, we'd be seeing a national population decline. Short of an economic catastrophe near-term (whether caused by Covid or other), I would expect Biden will get to enjoy a low unemployment rate in the next 2-3 years as well.
