It's a boring take from more than 30 years ago that was kinda true in the Regan years when the dominant voting groups could pretend that elected officials and government didn't actually matter because they all voted similarly and discrimination against groups that disagreed had been publicly accepted for decades. Historical electoral maps were not usually competitive at all like they are now.

The both parties are the same is such a lazy take, except in super limited circumstances like this naked power grab in the article. Both are going to use it in wildly different ways
