My original point really wasn't meant to say that both parties have the exact same view on any one specific political football, if that's how it came across then I explained myself poorly. My point was simply that, in my opinion, we've lost the classic left/right divide that was trying to find a balance between government powers and individual freedoms. Both parties in the US believe the government should have a say over nearly everything, from who you can love to what food you can eat. We don't have an option for a party that wishes to see keep government small by prioritizing individual rights. I may very well just misunderstand the core of the elft/right divide, but I was always led to believe that it came down to how big the government was, how much it spent, and what we can be told is/isn't allowed.
With regards to my point about abortion, it's much too detailed to put here and was probably an unhelpful distraction. But I don't see either party arguing that abortion should never be illegal, save for a few extremists both parties seem to agree that abortion should be illegal at some point and only disagree where that point is. Meaning, they disagree about whether that line is conception, birth, or sometime in between but both parties believe that they have the right to legislate what a pregnant mother can or can't do.
