It gives me hope that the left is. If the left shifts more central and becomes more palatable to centre right people than the far right, then the right also needs to shift.

It's of course always problematic to oversimplify the thousands of different issues and perspectives into simple "left vs right" or "conservative vs liberal" buckets, but overall, it's completely accurate to say that America has moved massively to the left, or alternatively, that liberals have been winning for decades.
The right-wing ideals of individual liberty & responsibility, of meritocracy and free choice have been completely obliterated from academia, media and public opinion. The entire narrative is owned and controlled by a left-wing view of race-based collective groups (which would have be class-based in Europe, but American left focuses more on race than class), along with an assumption that luck or privilege is the sole or at least primary driver of inequality.
On essentially every issue the left has not just won, but moved the goal posts of debate. You may just not notice it because you either agree with the moves or because which issues get focus aren't the ones you care about. The American left is doing little to solve climate change, pollution, affordability of middle class lifestyle, etc, but that's because they don't "really" care about those issues. They're winning on LGBTQ+, winning on race-based initiatives, winning on government-controlled access to healthcare, winning on federal power expanding and state power receding, winning on narrowing free speech, winning on reducing religious freedoms and winning on government-controlled land use, government-controlled economy, etc.
I was a left-wing radical in college. Without really changing my stances since then, I'm now a left-wing radical on only environmental issues but basically a centrist on others and occasionally on issues of free speech or free association it's only the right defending those freedoms.
