Voters took note of the quality of each candidate, and Democrats were scrappier in the fight this time around to give a tight result. Voters did not know much of what Mr. Biden had done to cap healthcare costs in midterm elections for 36 governors races and for control of the US Congress. The pocket book issues mattered to voters with sharp increases in the price of oil and groceries, but less so than made out earlier and voters may have grasped the bigger picture.
The quality of candidates mattered and on the Republican side the influence of Mr. Trump in the primaries led to choosing weaker candidates because of their loyalty to Mr. Trump. In the end with a large turnout of voters on both sides the election was much tighter than expected. Democrats in each state did better using their own initiative and effort this time and were much scrappier in the fight for the Governors races and the Senate.
