Oh, God no!
It's always nice to be told who the people are who don't understand the Constitution.
What needs to be reformed in the Constitution, which was acknowledged by the Framers to be an imperfect document?
Well, we need Judicial Term limits and a stated cap on the number of judges on the courts.
The country needs to grant the Congress and the states, both, a mechanism to reject false Supreme Court rulings.
The word "commerce" in the Constitution means "trade". It does not mean either "agriculture" or "manufacturing". The disaster area that happened when the Congress turned "commerce" into "anything we want it to mean" is never ending. The courts have even ruled that a farmer selling his grain locally violated Roosevelt's price controls, claiming that since the local sale of grain at a lower price affects the sale of grain from other states, then the Commerce clause grants Congress the power to regulate how and to whom local farmers can sell their produce, even when that does not cross state lines.
The nation NEEDS a uniform Voter ID law.
The Sixteenth Amendment needs to be repealed. The national treasury should be financed by a retail, final-user only sales tax.
The Electoral College has to be reformed, so that the delegates are awarded on the following basis, that the candidate that gets a plurality in a Congressional district gets the one elector allocated for that district, for each district in the state, and the candidate that wins the plurality in the state gets the two electors designated for the Senate Seats. No more winner take all shenanigans, and this changes the entire strategizing of a national political campaign. No longer is "Ohio" a "swing state", suddenly what's important is the individual congressional districts. Suddenly New York isn't determined by the Rodent that gets the voter-morons in that anus of a city, New Yorkers in the consevative upstate have a stronger say.
The Decennial National Census should ONLY count US citizens for purposes of representation apportionment. This is only possible if the Census demands the citizenship/residency status of all respondants. And there's nothing wrong with sending authorities to investigate respondents who decline to state, state their presence is lawful, or even to do random background checks on those claiming to be citizens. Lying on the Census is, of course, perjury.
A 3/5 vote in both Houses should be required to raise taxes. Tax cuts should be permanent until voted to curtail. Tax hikes should have an expiration date.
Laws should have Expiration Dates.
And the President should have line-item veto authority on all spending requests.
And it doesn't matter what nonsense an Article V Convention of the States proposes as recommended Amendments...it can't become an Amendment if the States refuse to ratify it. What must be done, of course, is to repeat the safety valve they installed on the so-called Equal Rights Amendment, and put a drop-dead date on each proposed Amendment.
