Trump should shut up and be quiet. Biden’s gaffes are the biggest possible pro-Trump messaging and Trump is simply lettinng him talk and make a fool of himself. Rope a dope baby, why draw attention away from the old duffer’s madness? Plus the Democrats are piling on him, if Trump enterss the fray they will lay off Biden and gang up on Trump. Is that what you want?
Good point. It's like a family with more than one brother - or even sisters.
They may bicker and fight amongst themselves, even resulting in the occasional bloody nose or fat lip. But as soon as some other kid starts trouble with one of them, they forget their spat and protect their sibling(s).
