Well, duh... It would be a cakewalk for Dems, if they willing to embrace policies that are proven winners by polling, like lowering health care costs, providing M4All, etc. and other lefty populist policies, but they never will, at least not sincerely, because it would anger their corporate donors. So they go on, election after election, trying to squeeze out, or not, a tiny marginal victory by basically saying, " We're not them!", and playing entirely to political theater, ID politics, and culture war issues. By now most Americans have seen this game long enough and either don't buy it or just give up on voting... Leaving all the populist positions to the Repubs, is not a winning strategy, but winning fed elections has not been a Dem priority ever since Clinton won in 1992.
