Undue burdens on the ability to vote in elections for Federal office prohibited

(a) In general Every citizen of legal voting age shall have the fundamental right to vote in elections for Federal office. (b) Retrogression A government may not diminish the ability to vote in an election for Federal office unless the law, rule, standard, practice, procedure, or other governmental action causing the diminishment is the least restrictive means of significantly furthering an important, particularized government interest. (c) Substantial impairment A government may not substantially impair the ability to vote in an election for Federal office unless the law, rule, standard, practice, procedure, or other governmental action causing the impairment significantly furthers an important, particularized governmental interest. A substantial impairment is a non-trivial impairment that makes it more difficult to vote than if the law, rule, standard, practice, procedure, or other governmental action had not been adopted or implemented. An impairment may be substantial even if the voter or other similarly situated voters are able to vote notwithstanding the impairment.
