What they are really pissed about is they don't have enough dirt on Trump to destroy him in favor of a candidate who will lose to whoever the RATs nominate, and that includes Joe "Plugs" Biden.
I like the way he talks about how rich he is. This takes it off the table for the dems, because they can't spew the "he's too rich" line the way they normally do. Trump wants folks to know what a money machine he is. They can't stand it. No playbook to deal with the Trump.
