Along with the usual "the cruelty is the point" responses, I'd like to remind people that this is a direct strategy championed by Mitch McConnell, who has been championing this strategy long before Biden came along.

First, McConnell believes that the GOP should not have any policy positions on anything at all. If you have a policy position, that position is subject to criticism. Rather than champion policies that he fully admits would be unpopular with the voters, McConnell believes in simply pointing to the Democrat policies, pointing out the flaws in those policies, and just making vague promises that the GOP can do better without actually defining how. Ever seen the meme of the guy tapping his own head while saying something profoundly stupid? That's exactly what this is. Picture McConnell doing that while saying "Can't be criticized for your terrible ideas if you just don't have any ideas at all!"

The other part, also championed by McConnell and others, is that no matter what it is, if it originally was a Democrat idea, then a Republican must be against it at all costs. Not only must they be against it, they must treat every Democrat policy as a threat to American society as we know it. Take a look at Romneycare in Massachusetts. A healthcare bill created by a Republican that was considered widely successful and basically the cornerstone to Obamacare. But the second a Democrat suggesting nationalizing the program, it was suddenly the worst program in the world that would collapse our healthcare system and lead to death panels.

And sad to say, but it's been a very effective strategy for them. It's easy for the GOP to get their voters to blame Democrats for problems because deflecting blame is easy, and people are always looking for someone to blame for whatever problems they have in life. People tend not to do their own research or critical thinking and often just prefer to be "told" what the "right" answer is, especially if what they're told jives with their own personal worldview. If voters want to believe that Democrats are the root of all evil, and their elected leaders are saying that Democrats are the root of all evil, it's not much of a stretch to get them to believe that anything or any ideas associated with Democrats are also evil and must be eradicated.

It's all about maintaining political power through obstruction. Doesn't matter how bad your own policies are just as long as you continue to make sure voters believe that the alternative is even worse.
