That's just another cynical "both sides are bad" argument. Judge the parties by their actions, not some vague handwaving about the Pareto principle and that all politics is corrupt.
From what I've seen, there's one party that has done more to disenfranchise voters and attack our democratic processes in the last year than I can remember in my entire lifetime. Attacking the postal service during a historic mail in election, inviting foreign influence into the election and directly soliciting it in exchange for military funding (and then getting impeached for it), the constant suggestions that the election is illegitimate so that he can scream and shout about it if he loses. The Trump reelection campaign (yes the political campaign itself, not even a neutral government entity) has also been litigating to make it harder to vote across the country.
At this point, coming to an article about a republican administration committing pretty clear voter suppression in the context of the past year of partisan voter suppression and saying "well actually, both sides are bad" is basically gaslighting. All sorts of voter suppression tactics like hardcore voter ID laws, purging the voting record (and "accidentally" getting rid of hundreds of thousands of legitimate voters), poll taxes by proxy, and crazy voting deadlines, restricting resources for polling places, and making it harder to leave your job to go vote leans to one side of the aisle.
