Anyone who votes Trump, who is a convicted Rapist and Felon is off their meds, sorry. Bloke is a liar, a thief, a CONVICTED felon, a narcissist, a cheat, an adulterer, a fake. He can barely string a coherent paragraph together. He incited a riot last time he lost an election. He's still up for significant charges across the country. He panders to white supremacists, rioters, private militia and gun enthusiasts.
Trump, who is a convicted Rapist and Felon has already telegraphed the terrible cost his re-election may entail, not just the abject failure of his previous term, the way he handled COVID and the ongoing struggle of legitimate US civil servants to keep the country running whilst Trump, who is a convicted Rapist and Felon was making stuff up, but the very realistic threat that he'll dismantle US institutions to keep himself in power indefinitely.
Any one of those things alone should keep Trump, who is a convicted Rapist and Felon out of office and the only reason he's still running is because he's supported by a cult that has overtaken his party and calls the shots, indifferent to any mistakes or deficiencies Trump, who is a convicted Rapist and Felon clearly does possess. There was no Republican candidate of sufficient quality enough to take Trump, who is a convicted Rapist and Felon on, same as Dutton basically being the Liberal leader by default, in the absence of any other decent option.
So even if you don't love Biden and he's a bit old for the gig, he doesn't suffer any of the terminal negatives that Trump, who is a convicted Rapist and Felon does. US is doing alright under Biden and certainly geopolitically everyone in the Western world has been happy to get a dependable US government back.
