Speaking to people does not constitute facts concerning what will happen in a future event. You have nothing but your own impression of what might happen. I'm not saying you haven't thought about or have what you think is a solid basis. But don't fool yourself into thinking you have facts about future events, those don't exist.
My basis for thinking that Leftists would be more than happy to get an Article V going? They have proven a solid desire over the last 100 years to destroy individual rights and replace them with group rights. To that end, they have not let intellectual honesty, fair play, or equal treatment deter them.
So, in summary. My best guess of what would happen don't line up with your best guess, because I have never met an elected Democrat in my life (and that is who would attend) who is a defender of personal liberty. I do not trust them, because in the last 50 years they have proven themselves untrustworthy.
The next step however, might be civil war, with a few heavily populated blue states trying to secede.
I think you have to take the democrat party and break into the camps. There are progressive democrats and liberal (classical sense before progressives assumed that name) democrats.
You are correct to not trust any progressive...regardless of party. I have met those too and they scare me. Think of T. Roosevelt, W. Wilson, FDR, J. Carter, B. Obama and H. Clinton. They believe there is not a reason to fear a larger government because they are in control.
True liberals fear a large central government. Just a true conservatives fear a large central government.
You rarely find progressives occupying space with a state government because they believe the federal government is where they should be to get what they want done.
The unusual aspect of an article V versus the federal government attempting another constitutional amendment is that the states will not give the fed any more power today. They are in a literal stale mate.
Why do you think you saw an explosion of Amendments at the turn of the 20th Century but none sense? Because with what was gained during the progressive age, they have been able to re-shape this country into a similar European government.
Do you believe that state legislatures are looking to dump more of their limited authority on the federal government.
“Democrat... who is a defender of personal liberty.” Here is a recent example (only 1, too hard to find before dinner) of a democrat standing up for personal liberty with the NSA. Do they disagree on social programs. You bet, but on this issue the are of the same voice.
