Chaos in Congress: Can the grand old party unite its flock ahead of assembly elections?

Congress has been on the backfoot ever since BJP came to power at the Centre. And now with assembly elections approaching in some states, things have not changed for the grand old party. It's just been in news for infightings, defections, blamegames, and chaos, which is stopping it from uniting and bouncing back. So, how long it will take for the Congress to get its together and can it even pose a challenge to the BJP's Modi-Shah jodi?
