It's not radical lefty stuff. It's a solid left turn though and not one designed to unite.
I have issues with some of the executive orders that are straight, as was put earlier, virtue signalling. They aren't there to do any good. In fact some of them do more harm than good. They're issued to check liberal boxes and show that Biden is taking a progressive direction.
Specifically, the change of the name of the US Ambassador to Israel. What good is done by that? The only practical effect was to piss off Israel. If that order doesn't happen, no one says a word. You can change the stance with Israel is a far more savvy way than this. It's a blundering move designed to signal to elements of his party that he's giving them what they want.
Then you have the Keystone pipeline. In what world is that a day 1 task? Trudeau, who no one would characterize as conservative, is a proponent of the pipeline and wanted to discuss the pipeline with Biden. But Biden wanted to pander to the left and give them their symbolic win that really doesn't have much effect.
Basically, Biden is making symbolic moves to satisfy the left that have real world net negative impacts.
