As a liberal, I would agree that there is some truth to the idea that if Warren were a Republican, that left-leaning politicians would tear into her more about the Native American thing. She would probably be branded with one of the label-du-jours, “cultural appropriation” or some such.
It’s why being a leftie, I try not to fall into lockstep with every bandwagon the left’s politicians are currently saying. When you’ve been around as long as I have, you start to notice that the left and right flip-flop on some of the issues. For example, years ago it was the left promoting tariffs and the right who were opposed to them. I wish the two sides, and the voters, would do a better job of prioritizing their fights.
It’s funny to see polls on the state of the economy. Obama was in office, Dems said the economy was good and Repubs said it was terrible. The minute Trump took office, Dems said the economy was terrible and Repubs said it was good.
