While control of both houses in Congress and the Presidency makes it easier for Biden and the Democratic party to pass highly partisan agenda items, it does not necessarily mean that is more likely for several reasons.
At present, Joe Biden appears well enough equipped to pursue the majority of his agenda, staunchly if not aggressively. However, his immediate actions are not likely to be particularly significant on the global stage as Democrats initially seek to counter much of what Trump and the GOP instituted over the last four years. The 2020 election has already set the stage to expand that sphere of influence in ensuing elections, but we are unlikely to see Biden push a radical agenda with an eye toward further consolidating that power in the 2022 ‘midterm’ elections.
The 2020 United States election always shaped up to be a crucial one on multiple fronts, and certainly delivered on the simultaneous promises to produce significant uncertainty and anxiety.
