The wolves have been in the government chambers, including the White House, since the founding. It's one of the most common threads of history.
Some 250 years ago on the east coast of what is now the USA, a group of the wolves got together and agreed to a new form of détente. Instead of trying to get rid of the wolves, they accepted that they themselves were wolves to a large sector of the citizenry, and they agreed to a set of rules that did _not_ make the citizenry free.
There is no way to force people to be free.
The new rules they set rather support a people that is willing to be free in their freedom by keeping any of the various factions -- the wolves -- from getting an upper hand.
Partisan politics (DNC, RNC, any other party that might develop long-term viability) is the result of certain factions collaborating to break the rules of détente -- factions within the party. That's why you have extremists along with moderates, and various flavors within the parties.
This is one of the things everyone who wants to be free needs to understand. The very existence of only two controlling parties is because most of the factions have agreed to try to break the détente. They think they will somehow win in the resulting power struggle.
The constant veering back and forth from left to right, liberal to conservative, etc. is a necessary adjustment in keeping any one faction of the wolves from taking control.
That's why the leaders of the parties don't like a loose cannon, except when they are the ones who haven't been in control.
That's why I'm really upset with the DNC for pushing RFKjr out of the contest this time. The two ruling parties have gotten too good at colluding with each other, and a win -- or even a serious challenge -- from a third party will force them back into détente.
Moderates are generally politicians who are willing to keep the détente. Biden was a good moderate until part way through his first term, when he ran out of energy to keep his party hacks -- his support team -- in check, and they took over.
Harris, as I say, is a loose cannon, too. She's good at hiding it. But if she had been elected, there would have been a lot of surprise and cries of betrayal from within the party that was hoping for another president they could manipulate.
