I definitely blame the democrats. They're the ones that have put Trump in the White House twice. I'm not talking of 'letting it happen', the dnc have actively done everything in their hands to make him president both times.
Edit: If you can't, or don't want to see it I'm not gonna try to convince you. This meme over here speaks volumes by itself– the dems not just can't reach the blue collar workers, who should be their main demographics, they've alienated, and even antagonized them to the point that many voted for Trump (I'm not saying this is a sane reaction! But people would grasp to straws). So yeah the 'insufferable tubs of shit' are the working people not the billionaire owners of the party.
I don't think anyone is asking for perfection just basic human decency, but I guess that's like asking for a thousand talking unicorns in politics.
