Ah it is about that time of year when people start saying "boy there's no way <candidate> could get elected - the market/sky/etc would fall!"
Sure reminds me of a time the silent majority elected a mango with a groping problem into office. I'm positive the silent majority could make it happen across the aisle too.
It would be wise to realize Biden would wipe the floor with Trump almost overnight, and Warren would give him a significant run for his money. His rallies are smaller than his hands after all the recent controversy and both of his major opponents have literal years of tape and twitter rants to use to erode his character. It will truly be a miracle if the RNC doesn't give a supermajority to the dems in 2020.
