Given the current results on SUSY searches at the LHC, the absence of the spectacular events of large hadronic activities plus substantial missing energy implies that new colored supersymmetric particles may not have been copiously produced. Current search strategies for those heavy colored particles typically involve large H_T or MET cuts, which are less sensitive to light electroweak interacting particles. In anticipation of much heavier colored SUSY partners, we are thus led to consider a less ambitious search strategy, namely the SUSY signals only from the electroweak sector, the charginos and neutralinos. We would like to address the question that to what extent in the parameter space, the SUSY signals from the electroweak sector are observable at the LHC.
