Three amici curiae briefs have been filed in the U.S. Supreme Court in Thompson v Hebdon, 19-122. The issues are Alaska’s $500 limit on individual contributions to candidates for state office, and the strict limit on how much money a candidate may receive from individuals who don’t live in Alaska.

Here is the amicus of Cato Institute and the Institute for Justice. It is concerned solely with the $500 limit.

Here is the amicus of the Institute for Free Speech, which is also entirely concerned with the $500 limit, and argues that the Supreme Court precedents on contribution limits are hopelessly inadequate and should be re-evaluated.

Here is the brief of the National Republican Senatorial Committee, which is also concerned with the $500 limit, but argues that the lower courts in this case improperly considered public opinion polling when they upheld the Alaska limits. The brief argues forcefully that the courts should not adjudicate First Amendment cases based on whether the restriction is popular.
