Is California's anti-SLAPP law constitutional?

QUESTIONS PRESENTED Is California’s anti-SLAPP law which allows California to ban Republicans from assembling and running for office as a “matter of public interest” in violation of the U.S. Constitutions Right to Assemble? Does California’s anti-SLAPP law which redefines Federal white-collar crime and political influence peddling as legal as a “matter of public interest” cause a conflict between California and Federal law that needs to be decided by the highest court? Can you apply California’s anti-SLAPP law against Republicans and not Democrats or does that violate the U.S. Constitution’s equal protection clause? Similar anti-SLAPP laws have been struck down in other states as unconstitutional as it deprives citizens access to a jury trial; shouldn’t the California anti-SLAPP law be struck down on similar grounds?
