The Tenther movement is a social movement in the United States, whose adherents espouse the political ideology that the federal government's enumerated powers must be read very narrowly to exclude much of what the federal government already does, citing the Tenth Amendment to the United States Constitution in support of this. The text of the amendment reads: Despite the movement's assertions, the Supreme Court has interpreted the Tenth Amendment such that the Amendment does not require a narrow interpretation of the federal government's enumerated powers. Instead, the Tenth Amendment makes clear that the powers of the federal government derive from the states voluntarily surrendering part of their sovereign powers. The Supreme Court affirmed this view in United States v. Darby Lumber in which the Court stated that the Tenth Amendment "states but a truism that all is retained which has not been surrendered ". In summary, members of the Tenther Movement believe that the Tenth Amendment should be interpreted as requiring that the federal government's enumerated powers be construed narrowly. In contrast, the Supreme Court interprets the Tenth Amendment as a default rule. In the absence of enumerated federal power, each state is the supreme sovereign of its own territory, but that this rule has no bearing on interpreting the scope of an enumerated federal power.
The Tenther movement is distinct from libertarianism, although adherents of the two philosophies often have similar positions. Whereas libertarians oppose programs such as the war on drugs on ideological grounds, seeing them as unjustified government intrusion into lives of its citizens, Tenthers hold that such programs may be perfectly acceptable, but only when implemented by individual states.
States' rights
Tenthers argue for the recognition of limited sovereignty of the states. Opponents use the term in order to draw parallels between adherents and 19th centurystates' rightssecessionists as well as the movement to resist federal civil rights legislation. Tentherism was also one of the justifications cited by pro-slavery advocate John Calhoun before the Civil War.

, a RepublicanSenator since 2015, said in a September 2013 forum held by the Iowa Faith and Freedom Coalition while she was a member of the Iowa Senate that Congress should not bother to pass laws "that the states would consider nullifying", referring to what she describes as "200-plus years of federal legislators going against the Tenth Amendment's states' rights". Ernst's statements were criticized in an article published by the United Press International on the grounds that they were based upon a misunderstanding of Tenth Amendment case law. In a weblog post for Reason, journalist Radley Balko objected to the name Tenther as the term originated as a pejorative used by those opposed to the movement's ideas in an attempt to reference and draw parallels to conspiratorial movements such as Birthers and Truthers.''
