I am a native Bangalorean. And from what I know of history our state. Close 99.99% of IT growth work you see today was the work of Deve Gowda(JD-S) and SM Krishna(Congress). On top of that biggest projects were conceived under Congress- IT Park constructions, Bangalore Metro etc.
Not a single thing has happened under BJP. The biggest scam in Karnataka's history mining scam happened and was done by BJP MLAs.
Avoid venting your political opinions here. like 'intended' user mentioned rationally there is hardly a party in India which isn't corrupt.
