The Democrats have been dismantling the Constitution for over 100 years, but you on the left have been fine with it for all this time.
That means it's OK with you, if Dems do it, but not if Repubs do it, when it comes to your own ideology.
Examples?
Established the Federal Reserve Bank
Federal Taxes
The people electing our Senators instead of our States
Supreme Court ruled six of F. Roosevelt's eight major New Deal statutes Unconstitutional
New Health Care Act forcing Catholic Hospitals to go against their freedom to exercise their religion
PC Police
Forbidding the press to enter the halls of congress
Forbidding certain popular gun sales and ammo
Totally ignoring the duties listed in the constitution and growing the government into a monster so that it can't be managed.
