Cite as: 558 U. S. ____ (2010) 23 Opinion of the Court and dissemination of ideas,” for “effective public communi cation requires the speaker to make use of the services of others”). If §441b applied to individuals, no one would believe that it is merely a time, place, or manner restric tion on speech. Its purpose and effect are to silence enti ties whose voices the Government deems to be suspect. Speech is an essential mechanism of democracy, for it is the means to hold officials accountable to the people. See Buckley, supra, at 14–15 (“In a republic where the people are sovereign, the ability of the citizenry to make informed choices among candidates for office is essential”). The right of citizens to inquire, to hear, to speak, and to use information to reach consensus is a precondition to enlightened self-government and a necessary means to protect it. The First Amendment “ ‘has its fullest and most urgent application’ to speech uttered during a campaign for political office.” Eu v. San Francisco County Democ ratic Central Comm., 489 U. S. 214, 223 (1989) (quoting Monitor Patriot Co. v. Roy, 401 U. S. 265, 272 (1971)); see Buckley, supra, at 14 (“Discussion of public issues and debate on the qualifications of candidates are integral to the operation of the system of government established by our Constitution”). For these reasons, political speech must prevail against laws that would suppress it, whether by design or inadver tence. Laws that burden political speech are “subject to strict scrutiny,” which requires the Government to prove that the restriction “furthers a compelling interest and is narrowly tailored to achieve that interest.” WRTL, 551 U. S., at 464 (opinion of ROBERTS, C. J.). While it might be maintained that political speech simply cannot be banned or restricted as a categorical matter, see Simon & Schuster, 502 U. S., at 124 (KENNEDY, J., concurring in judgment), the quoted language from WRTL provides a sufficient framework for protecting the relevant First Amendment interests in this case. We shall employ it
