After being successful in making two JD(S) candidates withdraw their nomination in the crucial bypoll to fifteen Assembly segments, Chief Minister B.S. Yediyurappa (BSY) will start his poll campaign for BJP candidates from tomorrow. The Chief Minister, who had camped in the State capital for a week, is said to have worked out strategies for ensuring the win of BJP candidates in the bypolls, as winning is crucial for the survival of the BJP Government in the State, which came to power in July last after the collapse of the coalition Government. BSY is said to have directed his cabinet colleagues to campaign briskly for the party candidates in all the fifteen Assembly segments going to bypolls on Dec.5.
