Searches for supersymmetry are among the most exciting physics goals at run II of the Tevatron. In particular, in supersymmetric models with light charginos, neutralinos, and sleptons, associated chargino-neutralino production can potentially be observed as multilepton events with missing energy. We discuss how, in the generic TeV-scale minimal supersymmetric standard model (MSSM), the prospects for these chargino-neutralino searches are impacted by cosmological considerations, namely, the neutralino relic abundance and direct detection limits. We also discuss what an observation of chargino-neutralino production at the Tevatron would imply for the prospects of future direct dark-matter searches without assuming specific patterns of supersymmetry breaking.
