Vladimir Putin has expressly stated that he supports Trump and the Republicans in the upcoming election, like he did in the last one.
You call them "natural liberals." I don't see it at all. Russian society has many characteristics of totalitarian regimes: no freedom of speech, a ruler for life, and opponents who "disappear" or get poisoned. That's why they sympathize with Trump--same leadership style.
Now here's the thing: EVEN IF the Russians intervened on the side of the Democrats, I, a Democrat, would oppose them. Letting foreign powers undermine our system is just plain wrong, regardless of who benefits. The very fact that you would assume it's NOT wrong as long as the intervention supports your candidate shows me that you don't even understand what our election process is supposed to be about.
If you ask me, that's more unAmerican than anything the "squad" has ever said.
