Or rather, he should be, because Bloomberg is a far weaker candidate than either Sanders or Biden.
Whether or not Bloomberg actually is Trump’s dream opponent depends on how well the Trump campaign understands that the centrists in the DNC have their thumb on the scale in favor of a pro-Establishment candidate. My guess is that they understand that pretty well, given that they are working for someone who was himself a party outsider and therefore had to contend with the Republican version of the very same thing.
That means I was wrong when I answered my question about Sanders being Trump’s dream opponent in an earlier post.
Trump’s main goal when attacking Biden is to elevate not Sanders but Bloomberg, because Trump is fully aware that this will prompt the Democratic Party elite to do everything within their power to elevate Bloomberg.
