They are reading the whole Constitution on the floor of the US House today, and it seems to annoy the media and many Democrats. If these folks were smart, they would use the occasion to state their own views on the Constitution rather than protesting the "Constitution worship" with which they accuse Republicans. Instead, they have reacted as conservatives predicted, with attempted ridicule and petulance.
Conservatives are right to revere (they don't worship) the Constitution, along with the Declaration of Independence. At a singularly propitious point in a new country of only three million people, a uniquely remarkable group of leaders came together to establish by reflection and consultation the finest guiding document in political history. It is principled and yet capable of amendment. It has lasted longer than any comparable document.
Unfortunately, since at least the Progressive Era, the Left that supposedly trusts the people has sought to avoid the amendment process as a way of modernizing the Constitution and to change the document's plain meaning by judicial decree and administrative fiat. Today the new House leaders are calling them on it. So, what it is the Left is really feeling today is not amusement or annoyance, but embarrassment. The more liberal (er, "progressive") critics carry on, the more they reveal their ignorance and bias. A lot of Americans accordingly are getting a bit of education in civics.
