Key by-poll results are out in 10 seats and the BJP marches ahead winning 5. The Congress too doesn't do badly, winning 3 including a narrow win in BJP-ruled Madhya Pradesh. However, it is a huge setback for the Aam Aadmi Party, which loses its deposit in Delhi. So what do these results tell us? Is the BJP unstoppable or has the Congress shown it is still a force to reckon with, and is this the unravelling of AAP?
