I like Beshear but I think he isn't the right candidate as it is a fallacy to conclude what America craves is a centrist approach and a return to the same old same old.
That will not turn young voters or the democratic base out to vote. I attribute a lot of Trump's electoral success to the fact that, even though they were lies, he is willing to say things a moderate Democrats won't such as I will lower prices or I will do this or that.
The traditional Democratic approach has always been, even when in control
of all three branches, well let's see that issue is really tough. Because of lobbying and so on the best we can hope for is some small changes around the edges. I can't even promise that given the current environment but I will make an effort.
People are tired of that kind of BS. Things aren't going well for them and they weren't going well for them prior to Covid. They believe there is a real need to reign in corporate America and the Oligarchy. That we need real changes to our healthcare system, to our taxation system and to our legal system. That home ownership , a new vehicle and so on should be in the reach of people with a full time job.
If all the Democrats offer is a return to the status quo before Trump that might win them the 28 Presidential but you can count on a big 30 mid-term loss as well as a likely 32 Presidential defeat.
The specific problem with Beshear is that he is a centrist and that's a big ask for the base of the Democratic Party because we know that the current Republican Party is so far to the right it is a fascist party.
The centerist approach will
mean every problem that requires negotiation with the other party will result in best case a center-right outcome.
Regardless of how good a person Beshear is I won't carry water for a centrist approach that results in center right governance. I would likely opt not to vote if he is the candidate as a conservative "lite" Democratic Party is not for me.
