In by-elections to different state assemblies, these are the results so far.
The big highlights: Pro-Telenagana TRS, which is K Chandrasekhar Rao's party, does very well in Andhra Pradesh (six of the seven assembly seats that voted are in the Telangana region). Congress punished by voters for centre's refusal to sanction a separate Telangana state
In Gujarat, BJP loses Mansa assembly seat to Congress, worrying for the BJP since state elections are just months away.
In Karnataka, BJP lost the Udipi Chikmanglur Lok Sabha by-election seat which was former constituency of Chief Minister Sadananda Gowda. The BJP's tallest leader BS Yeddyurappa was not allowed to campaign here by his party because it was worried the corruption charges against him would turn voters against the party.
