I’m sorry but that is way too reductive. For one thing, there’s a bipartisan consensus (for better or worse) on a lot of foreign policy, which is a pretty huge area.
And, your comment obscures the meaningful differences in ideology between the groups of people each party represents. And the different interests of those groups.
The Democrats are far from perfect. But it’s not a “both sides equally bad” situation.
Well, maybe it is when it comes to corporate money in politics. But even there you see bipartisan consensus on the fringes, I think, plus iirc the Republicans were basically all about Citizens United.
But yeah money in politics is a big problem on both sides. To be fair, it’s been a big problem in all of politics throughout all recorded history.
Which doesn’t mean we can’t (and haven’t) made some progress.
