I already knew the answer - it was a rhetorical question
But an interesting discussion nonetheless. Joe - I agree with your concern, and I wouldn't support support packing the court in this manner for precisely the reasons you state. I am, however, amused that this technically perfectly legal approach is decried as an assault on liberty and egregious tyranny by the same people that gleefully, but in theory legally, denied Garland so much as a vote.
The larger point is that some group of people need to step back from the zero sum model of political behavior, even at the cost of short term gain. This assumes, of course, that the other side (we can call them "Republicans" for the sake of argument) would behave accordingly in response, and not just consolidate their power. They won't under Trump and (especially) McConnell, but maybe later...
