Yep, Ford, Bush, and Carter lost their re-election (yes, I know Ford wasn't up for re-election but work with me) when they had a bad economy or recession.
From 1900-1960, the only Presidents to lose re-election were Hoover in 1932 (GDP was down that year) and Taft in 1912 (the economy wasn't strong). Every other President up for re-election had a growing economy and, in turn, they won.
It's pretty clear that the ONLY thing that can tank Trump, aside from Dem fraud, is a bad economy.
Let's be honest: stocking up on food and staples isn't such a bad idea even if a Mainland China type of situation coming to America is hard to fathom. The problem arises when a Deplorable's natural distrust of the govt is manipulated in a judo move to derail Trump. To wit: why is Trump basically saying be cool and we got this...yet liberal and NeverTrumper elements in America - as well as Amazon with this unnecessary public utterance- and the Deep State are chatting up a pandemic?
The answer is, to sweep up folks normally supportive of Trump into the mania, and to bring about a recession and the demise of Trump.
