It’s an intro to the Constitution with no legal status.
I think without it, your Constitution is doomed as the anarco-communists use the Constitution to destroy itself.
The Founding Fathers certainly gave it weight by their words.
While the Preamble may have had particular relevance to a number of isolated questions before the Congress in the Nation’s early years, Presidents and congressional leaders have more generally relied on the Preamble’s laudatory phrases in exploring the broader import of the Constitution and the general purposes of American government. For instance, President James Monroe referred to the Preamble as the “Key of the Constitution,” 17 and in his inaugural address, President John Quincy Adams described the “first words” of the Constitution as declaring the purposes for which the government “should be invariably and sacredly devoted.” 18 Echoing these themes in his own first inaugural address, President Abraham Lincoln invoked the Preamble’s “perfect union” language to note the importance of national unity as the country faced the brink of civil war.19 In the midst of another constitutional crisis—that which arose in 1937 amid clashes over the constitutionality of the New Deal—President Franklin Roosevelt stated the need to “read and reread the preamble of the Constitution,” as its words suggested that the document could be “used as an instrument of progress, and not as a device for prevention of action.” 20 Decades later, Representative Barbara Jordan, the first African-American woman elected to the House of Representatives from the South, quoted the Preamble in a statement before the House Judiciary Committee as it considered the Articles of Impeachment for President Richard Nixon.21 In that statement, she noted that “through the process of amendment, interpretation, and court decision” she had been included in “We, the people” and was now serving as an “inquisitor” aiming to preserve the goals of the Constitution.22
