When Republicans held the presidency conservatives generally approved of an "imperial president" presiding over a Democrat congress. Ever since the Democrats grabbed hold of the presidency, not so much.
Now that Republicans hold most of the state houses we are seeing arguments against the 17th Amendment, against the Supreme Court decision in Reynold vs. Sims., and calls in favor of secession.
It was thought that the Republicans supported conservatism in opposition to the liberal Democrats. Now it seems to be believed that state legislatures will be the army to fight for conservatism in opposition to federal politicians.
If most state legislatures truly are stalwart conservatives then we can trust them to take control during any Article V convention. If, however, they are not then we can't trust them in an Article V convention nor trust them to take tax dollars and control away from the feds.
At least with an Article V convention we wouldn't be asking the state legislatures to do anything that could be considered illegal.
Good summary.
I would only add that anything ratified by three fourths of state conventions should be in the constitution. It is the nature of republican government.
As opposed to what our oppressors in DC would have us believe, it was supposed to be relatively easy to convene state conventions. The difficult part was thought to be getting three fourths of state conventions to ratify.
