He didn’t phrase it well, but I think what he meant is that Dems particularly hate opponents who’ve been the most effective and unapologetic, including Rove (way back when), and like the call them evil, Darth Vader, etc.
Bannon phrased it well and succinctly. He is not going to be an unqualified asset to the Trump administration. Such hubris as “...Satan is power” bodes trouble for Trump.
Further, he apparently supports Citizen’s United and for any true Conservative that case is anathema to any healthy nationalism. It brought us the flirt with corporatism and globalism Trump should be, and hopefully is. against or we get more G.H.W. and G.W. Bush destructiveness.
Watch out for Mr. Bannon. I am very leeery.
