  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 multi-lepton events with missing energy. We
discuss how, in the generic TeV-scale 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.
