If you really cared about qualifications, one need only look at the Bush vs. Gore election to see what the consequences of electing unqualified idiots are. There was basically zero chance we'd go to war in Iraq, for example, under a Gore presidency. Thousands of Americans were killed, tens of thousands more maimed, hundreds of thousands to perhaps a million Iraqis killed, dead, displaced. Because people thought Gore was boring or they wanted to stick it to the Democrats, or they hated Gore's global warming work.
When Trump fails miserably at something -- and goo people -- Americans -- die, it's on you, pal. He's not qualified and he never will be. And he doesn't even seem to care.
