Yes. Absolutely. BJP shouldn't have done that. They should have ensured somehow forming the government, a la Congress style (horse trading, buying off Kumaraswamy, threatning him, etc.).
Then they could have remained in control and ensured idiotic cases like illicit arrack don't occur.
That they couldn't do that clearly shows their inability to stick to power. Voters should keep that in mind and ensure that Congress comes back to power in Karnataka too - to stay for another 500 years.
If we could tolerate Mughals and the British for hundreds of years, why can't we extend the same invitation to Congress?
