Csj won't win as he is a big liability. . In fact sdp should surprise pap tactically by switching to PT. PT at the same time need to walk the ground everyday to cover as many block as possible. Csj should just stay away from any involvement. The last thing voters in bb will want is to be reminded how badly neighboring Bt gombak was managed when csj took over from cst. I expect pap to capitalize on this point.
