disenfranchising

Disfranchisement, also disenfranchisement or voter disqualification, is the restriction of suffrage of a person or group of people, or a practice that has the effect of preventing someone from exercising the right to vote. Disfranchisement can also refer to the revocation of power or control of a particular individual, community, or being to the natural amenity they have; that is to deprive of a franchise, of a legal right, of some privilege or inherent immunity. Disfranchisement may be accomplished explicitly by law or implicitly through requirements applied in a discriminatory fashion, through intimidation, or by placing unreasonable requirements on voters for registration or voting. High barriers to entry to the political competition can disenfranchise political movements. Read more on Wikipedia
