To be clear, when I talk about how both mainstream political parties are used to advance the same agendas I am not saying that they are the same. I like to compare them to the jab and the cross in boxing; they're two different punches thrown from different hands, and they're used in completely different ways. But they're both being used by the same boxer, and they're both being used to knock you on your ass.

The cross, which happens to come from the right hand for an orthodox fighter, is a damaging knockout punch. But in boxing it's generally worthless on its own; it might be useful in a pub brawl, but against a skilled boxer you need to set it up with the jab.

The jab — the left hand for an orthodox fighter — is a swift, stunning blow. You don't see many knockouts with it, but you see it land with great frequency because it's thrown by the hand that's closest to the other fighter. And the beauty of the jab is that it can be used to set up the cross — the famed "one-two", the most common combination in boxing.

That's how the two mainstream parties work together to knock the public on their ass. The "left" party sets them up, and then comes the crushing knockout blow. Democrats fight off all efforts to move the US to the left when they're in power, then Republicans come in and move it even further to the right. Democrats refuse to codify Roe V Wade, and Republicans come in to kill it. Democrats "reluctantly" give Bush war powers, he uses it to invade Iraq. Democrats inch up the brinkmanship against China, Republicans do whatever horrifying thing they're going to do when they take power.
