If Trump had done a good job, we would have been locked down for a month. But, he did a piss poor job as evidenced by the fact that we are now emerging, yet the outbreak is not under control. A large part of the unemployment now and later will be because of Trump's ineptness. While some may give him a pass (some will look the other way at him killing people on 5th avenue, which he did btw), those that are sitting unemployed in November will not. Of course, he will also have to deal with the ledger of deaths attributed to his ineptness, but that is another discussion.
Good for Trump that he inherited a good economy and then declared it his own. Unfortunate for him, he will exit with a poor economy which most people will fault him for. Good luck coming in; bad luck heading out. But, hey, better to have bad luck than no luck at all.
But, back to your point, why would anyone trust a Republican with their 401(k) when over the last 100 years the Dems have had 6.3x the returns of Republicans. You didn't answer that one.
