Nuts and bolts of federal front?

Nuts and bolts of federal front?

Mamata Banerjee. Chandrababu Naidu. Akhilesh Yadav. Mayawati. KCR.  The regional leaders have spoken.  They are thrilled about the coming together of the Congress and the JDS in Karnataka, never mind the possibility that the alliance might well be a short-lived one.  Will there be a third front? 

Firstly, many see a potential BJP washout if regional parties were to come together in 2019.  "Vote percentage in Karnataka is the best validation of federal front arg (especially of Mamata). Congress loses but gets 38%, which is 2% more than BJP's vote share. JDS gets nearly 20%. Clearly together they would have decimated the BJP. Such alliances are way to go in 2019 in every state with regional parties," Abhishek Singhvi of the Congress recently said.

However, such arithmetic is easier said than done.  Vote conversion isn't easy in elections.  As they famously say, in politics, 2+2 is not necessarily equal to 4.  A fence-sitter may vote for Congress if it's contesting alone. But he may switch to BJP or some other party if it allies with JDS.
