> That's somewhat ahistorical, the 17th amendment happened because state legislatures were frequently deadlocked and could not appoint senators, meaning states went without senate representation entirely.
That seems more like an excuse than a legitimate reason. If that was actually the problem you could solve it by adopting a mechanism to break ties, putting the vote to the public only in the event of a tie, having the state legislatures use score voting which makes two candidates getting exactly the same score far less likely, etc.
But if they want to do a power grab then they get further by saying "we have to do something about these deadlocks" than by saying "we want to do a power grab".
> That said the proper reform to this would've been the abolition of the senate, as it has always been and will always be an anti-democratic force
It's supposed to be an anti-democratic force, like the Supreme Court, the existence of Constitutional rights and the entire concept of even having a federal government instead of allowing local voters to have full plenary power over local laws. Unconstrained direct democracy is a populist whirlwind of impulsive reactionary forces.
