The only reason party politics exists is because of you and people like you who keep spouting this lie that keeps them in power.
So instead of lying just say that you fully agree with everything both parties do and thats why you keep them in power and refuse to vote for someone rather than against.
Something I read once, probably 50 years ago now: you may not see a candidate you want to vote for, but you will probably see a candidate you want to vote against.
The general difference between a liberal mindset and a conservative mindset is the difficulty in making things work. Liberals believe that things usually work and the hard part is getting them to work exactly how you want them too. The conservatives think that things usually dont work and the difficult part is getting them to actually work.
This actually really matters when your talking about renovations whether its a building or a government you have to choose between the new fancy shiny thing will all the options and the old beaten up reliable thing that only does one thing and does it really well.
When dems propose something new, all the reps see is every way that it could go wrong or even be worse than the last thing.
When reps oppose something new all dems see is stupid old people afraid of progress.
And thats assuming that everyone actually has good intentions before we get into partisan bs and outright corruption.
The dem-rep balance would actually be really great in the politicians gave half a fuck about the country but they arent trying to make the country better in good faith they are trying to win politics which isnt even possible, a win for one party means the end of the country no matter which party the country needs the balance i just laid out above. You need long term trusted institutions and you also need to change and update things over time. Both perspectives are necessary if you want a functional government this petty infighting serves no purpose besides allowing politicians and their corrupt friends to loot and pillage the country from the inside while the stupid population argues over men in womens sports or when child sacrifice is okay.
If yes, you might want to look at your information environment.
