There is a certain bias in the media against the BJP.
The Punjab problem was a creation of the Congress when they propped up Bhindranwale to cut the Shiromani Akali Dal to size. The Kashmir problem was created by the Congress and the NC when they rigged the 1987 elections. One of the candidates who lost due to rigging went on to become Syed Salauddin of the Hizbul Mujahiddeen.
Despite all this, the Congress party point fingers at the BJP. Kailasa and Manasarovar were handed over to China while Thinvida region was given to Bangladesh by the Congress during their rule
Probably the local vote banks in Bihar were not given any freebies to vote, no booze or money, so no stake in a democracy. After all Bihar is the richest state they claim, and so backward only because the centre does not want it to progress.
