Bcoz ppl tend to support the ppl who get scholdings from Gurus..
and one more thing is that Bonjyotsna(huge in number) supporters will think that she shldnt loose bcoz of Sharib's conduct..so almost their vote double.(B supporters).(So if we consider 50% of BS supporters r B supporters then they vote twice as before so Sharib supporters support him but his vote bank may get reduced anyway Thats enough for them to enter final-2.)...
Next May b UA'S turn to get eliminated
