A tug-of-war? Agreed. The see-sawing readings of the seats in the state is rather confusing, but it is clear that votes cannot be sold or snatched. They depend of the work that the candidate may have done. Congress witnessed a sudden blow with a steep fall at 37 as BJP rushed to the top at 45.
The deciding factor would be the last 5 seats left. However, even if Congress wins the last 5 seats in a single blow, there is a strong possibility that BJP may still win.
