Of course you don't, you're an idiot. If you're stupid enough to ask why is a president's popularity rating in the 8th year of his term relevant, it's no wonder you don't understand what "there is not enough evidence to bring charges" means.
You keep chantin' that, Sheriff Jagoff, see what good it does you. Meanwhile, there is a Presidential candidate going to court this month for having massively broken the law, and it's Rump for his bullshit foundation on November 28th. Somehow, I don't think November is a month that Rump is gonna remember fondly, lol...
