It is wrong on the part of BJP to have struck a deal with Gowda and his family. If you see the history of this family, they had ditched many alliances, like RK Hegde, SR Bommai, Dharam Singh, and now the BJP.
To refrain from giving power to BJP, they may seek Congress support. But Congress, should not come to any understanding with this JD-S knowing their history of cheating/betreyal.
I also wish, in the forthcoming election, the people of Karnataka give them a thorough white wash, and teach them a lesson.
