Karnataka is always in a shambles mode when it comes to CM's.
Yeddy is no brainer to loose. Yet he will be ousted from power, based on current planets position.
I think for sure - he will resign by end of the month. Mercury (communications, is in retrograde) and hence this will downfall based on Venus ( relatives, siblings, etc.. wrong doings. )
Based on current situation Shobha Karandlaje would be the best bet to take CM post.
