preclearance from the Justice Department under the 1965 Voting Rights Act? If Lampson appears twice on the ballot it will confuse voters. They may vote for him once to fill out the unexpired term and not realise they will have to vote for him again for the new term. Under the 1965 Voting Rights Act a covered jurisdiction (and Texas is) must "preclear" voting changes that might result in discrimination against minorities. The covered jurisdiction has the burden of proof to demonstrate that the proposed voting change does not discriminate. Even if Lampson is smart enough not to take the bait and file for the special election, having the same office appear twice on a ballot would certainly appear to qualify as a change that might be confusing enough so as to discriminate against a "language minority group."
"Section 5 of the Act requires that the United States Department of Justice "preclear" any attempt to change a voting standard in a "covered jurisdiction." A covered jusidiction that seeks to obtain Section 5 preclearance, either from the Attorney General or the U.S. District Court for the District of Columbia, must demonstrate that a proposed voting change does not have the purpose and will not have the effect of discriminating based on race or color. In some cases, they must also show that the proposed change does not have the purpose or effect of discriminating against a "language minority group." Membership in a language minority group includes “persons who are American Indian, Asian American, Alaskan Natives or of Spanish heritage.” The burden of proof under current Section 5 jurisprudence is on the covered jurisdiction to establish that the proposed change does not have a retrogressive purpose.<6>
Covered jurisdictions may not implement voting changes without federal preclearance."
