More importantly, it's a brilliant tactic that the Harris campaign is stealing from Trump. 

Notice how no one on the left is talking about this unrealized tax plan. But nearly everybody on the right is spending 80% of their time on it. 

So instead of talking about the realistic failures of plans that will get enforced, like more failure on the border, like the drug epidemic spiraling out of control, the health crisis getting worse, etc.... "we" are spending hours and days talking about something that won't happen. 

It's brilliant politics. 

And its working.
