Victor Davis Hanson sees the problem Democrats face.
Democrats privately acknowledge that Obama wrecked the Democratic Party—losing Congress, the presidency, state and local offices, and now the Supreme Court. But they must praise the forces of that wreckage and seek to trump them by becoming the party of hyper-identity politics. In other words, the Democrats know what sort of agenda might bring them back into power as it did in 1992. But they feel that Clintonesque cure is worse than the disease of being in the purer political wilderness without power.
So, for now, they rant, they rave, and they stew, accepting that they cannot do what might save them and therefore they only do more of what is destroying them. Out of that lose-lose dilemma was birthed Trump hatred. Without a persuasive argument, progressives came up with the mantra that Trump is a traitor, and that all they needed to do was to explain to supposedly dense voters that their current economic renaissance was actually jackbooted National Socialism.
