Sun Tzu said it best: Never interrupt your enemy when he is making a mistake. Trump is letting the Democrats destroy themselves first.
It’s great. Trump can use the democrats own quotes about each other in a campaign commercial.
Actually, if you listen to Trump carefully, he is offering his assist, and you can tell that he wants Bernie. He is attacking Bloomberg heavily all while claiming the DNC is railroading Bernie again. He is telegraphing what he really wants.
Bloomberg may have a LOT of flaws, but he is not a democratic socialist. Trump knows this, and he is also intimately aware how how powerful a propaganda machine the MSM is, even without the kind of money that Bloomberg has. Bloomberg is definitely the bigger threat. They can prop him up both as the savior to all the desperate democrats, but as the moderate to all the independents.
