That's because you only hear what you've tuned your Fabian socialist ears to hear.I don't see any dems claiming to be Originalists or Strict Constructionists, or claiming that the Constitution has been "corrupted"
Constructionists also abhor the corruption of original intent that are the 14th, 16th and 17th Amendments.
There is no such thing as "original intent". That's a phony premise that would have us believe that all the Founders were of the same mind. There were actually "original intents", which is why we have a relatively short and in some ways vague document, necessitating courts to make interpretations. As Jefferson said, it's for each generation to decide what it means and that we're not bound to their interpretation.
"I am not an advocate for frequent changes in laws and constitutions, but laws and institutions must go hand in hand with the progress of the human mind. As that becomes more developed, more enlightened, as new discoveries are made, new truths discovered and manners and opinions change, with the change of circumstances, institutions must advance also to keep pace with the times. We might as well require a man to wear still the coat which fitted him when a boy as civilized society to remain ever under the regimen of their barbarous ancestors. Thomas Jefferson
Thomas Jefferson quotes
"Original intent" is a made up concept that doesn't actually exist in constitutional construction. And while Jefferson's words were nice and offer guidance, they aren't enforceable as law. Jefferson, Madison, et al, while great men, were no more than the politicians of their day. It isn't for them to tell later generations how to INTERPRET the words of the constitution.
And what the wingnuts seem not to understand is that words need to be interpreted. They do not exist in a vacuum.
And the concept that an Amendment can be somehow "unconstitutional" shows that they have no understanding of what the word unconstitutional means since, if it is part of the constitution, whether via the original words or later amendment, it is, by definition, Constitutional.
But the loons don't like the constitution. They only like what they want to pretend it is.
