Bhabha scattering with polarized electrons at the {ital Z}{sup 0} resonance has been measured with the SLD experiment at the SLAC Linear Collider. The first measurement of the left-right asymmetry in Bhabha scattering is presented, yielding the effective weak mixing angle of sin{theta}{sup eff}{sub {ital W}}=0.2245{plus_minus}0.0049{plus_minus}0.0010. The effective electron couplings to the {ital Z}{sup 0} are extracted from a combined analysis of polarized Bhabha scattering and the left-right asymmetry previously published: {upsilon}{sub {ital e}}={minus}0.0414{plus_minus}0.0020 and {ital a}{sub {ital e}}={minus}0.4977{plus_minus}0.0045.
