In an action brought by the Libertarian Party of New Mexico and four of its candidates for public office alleging New Mexico's two-petition ballot-access scheme unconstitutionally burdens their First and Fourteenth Amendment rights, summary judgment for defendants and denial of plaintiffs' request for discovery are affirmed where: 1) based on a Fed. R. Civ. P. 56(f) affidavit's lack of specificity, the district court did not abuse its discretion in denying the request for discovery; and 2) plaintiffs failed to provide evidence showing that the burden of New Mexico law is severe as to minor party candidates, and thus there was no genuine issue of material fact for trial as to an essential element of their claim.
