We make a systematic and comparative study for the LHC and ILC for the
electroweakino searches in the Minimal Supersymmetric Standard Model. We adopt
a general bottom-up approach and scan over the parameter regions for all the
three cases of the lightest supersymmetric particle being Bino-, Wino-, and
Higgsino-like. The electroweakino signal from pair production and subsequent
decay to Wh (h to b\bar b) final state may yield a sensitivity of 95% C.L.
exclusion (5sigma discovery) to the mass scale M_2, mu ~ 250-400 GeV (200-250
GeV) at the 14 TeV LHC with an luminosity of 300 fb^{-1}. Combining with all
the other decay channels, the 95% C.L. exclusion (5sigma discovery) may be
extended to M_2, mu ~ 480-700 GeV (320-500 GeV). At the ILC, the
electroweakinos could be readily discovered once the kinematical threshold is
crossed, and their properties could be thoroughly studied.Comment: 12 pages, 3 figure
