Even if your wildest wet dream come true and AAP wins Delhi and Punjab, could they win UP? Bihar? Maharashtra? Karnatka? Madhya pradesh?..............
You are forgetting a devastation that united Hindu front could visit in anti-Hindu parties. Congress ,barring it's last 5 year regime, was not an out and out anti-Hindu party. It was explicitly anti-Hindu party for last 5 years and result are for evryone to see.
AAP, a anti-Hindu, communist, terrorist supporter, Party of NGO's would never grow outside Delhi and to some extent Punjab.
