You know as a liberal I'm not necessarily opposed to Senate by State Legislature, I think it would help make people more aware of theit state elections more. I think a new amendment could be fitted with rules that avoids the issues that brought about the 17th to begin with (corruption, deadlocks, different rules) so maybe you pair it with some standardized rules for the Houses on how the selection works.
It is not the only systemic issue though for sure so surely we can agree also with expanding The House, a full gerrymandering ban nationwide, maybe enacting proportional representation, since we are talking about original, spiritual intent here that is just as if not more important.
It failed, objectively by any measurable metric it failed.
No, it succeeded in *some* of its goals. It reduced the number of uninsured, helped many millions who did not have access to insurance gain access. The preexisting conditions change is so successful and popular that Republicans and Trump try and take credit for it. Also while it's biggest failure was controlling costs it also very much kept the rate of rise in costs down from where it was pre-2010 and where it was expected to go from there.
It certainly didn't help that Republican's refused to partake in any of it, have sued and their media has lambasted it at every turn and then picked it apart piece by piece.
Now the rub for the folks who dislike the ACA is that it is in fact the conservative health insurance system and the only viable replacements are the systems elsewhere in the world which are more subsidized and regulated. It's why we haven't seen the "replace" and only "repeals".
It's either go more socialized or bring back the early 2000s' era which is not a great campaign issue. Good luck.
