Just ask Trump what will happen if he’s not re-elected. He gets very apocalyptic.
Don't listen to Trump - take him out of the equation. Take COVID-19 out of the equation and its effect on the economy, as well - it was a disaster that could not have been averted due to the actions of the Chinese.
Prior to all of this the economy was a freight train, the strongest in decade, lowest unemployment in decades - in some cases ever, stock market hitting record highs, Obama Diplomat appointees testifying that foreign relations under Trump being better, etc...
Now compare that to the promises made by his Democrat opposition:
Higher taxes
A reversal of every successful economic policy
Fewer jobs, elimination of jobs/higher pay/raises/bonuses
Insane new policies - like outlawing the internal combustion engine and use of fossil fuels
Reliance for energy on technology not even developed yet
Higher number of Americans on food stamps, welfare, etc...
Outlawing privately owned health care
The alternative is not 'apocalyptic', but they are completely opposite sides of a coin.
Of course one can not simply take COVID-19 out of the equation - the country has forever been changed, and I am not just talking about 'social distancing'. 'Government' took massive steps forward in growth and power / authority it used to override Constitutional Rights in many cases. And Liberals could not have asked for a greater early 'Christmas present' to help push their agenda of bringing about a Socialized Single Payer health care system than COVID-19.
From that to the new TRILLIONS of dollars being added to the debt to keep the nation's economy's heart beating and to kick start it when 'all this is over', the country was thrust into a whole new uncharted course due to COVID-19 which is going to need a new plan. There will be no 'picking back up where we left off' before COVID-19 because so much has changed and so much is different now.
