             abstract = "We present the first population synthesis of synchronous magnetic 
                         cataclysmic variables, called polars, taking into account the 
                         effect of the white dwarf (WD) magnetic field on angular momentum 
                         loss. We implemented the reduced magnetic braking (MB) model 
                         proposed by Li, Wu \& Wickramasinghe into the Binary Stellar 
                         Evolution (BSE) code recently calibrated for cataclysmic variable 
                         (CV) evolution. We then compared separately our predictions for 
                         polars and non-magnetic CVs with a large and homogeneous sample of 
                         observed CVs from the Sloan Digital Sky Survey. We found that the 
                         predicted orbital period distributions and space densities agree 
                         with the observations if period bouncers are excluded. For polars, 
                         we also find agreement between predicted and observed mass 
                         transfer rates, while the mass transfer rates of non-magnetic CVs 
                         with periods greater than or similar to 3 h drastically disagree 
                         with those derived from observations. Our results provide strong 
                         evidence that the reduced MB model for the evolution of highly 
                         magnetized accreting WDs can explain the observed properties of 
                         polars. The remaining main issues in our understanding of CV 
                         evolution are the origin of the large number of highly magnetic 
                         WDs, the large scatter of the observed mass transfer rates for 
                         non-magnetic systems with periods greater than or similar to 3 h, 
                         and the absence of period bouncers in observed samples.",
