PK has not won any elections, other than the student union one at JNU. He should try to stand for a municipal election first and then try to challenge a 10 time MP. The speaker looses his party affiliation once elected, Karat should know that. SC did a wonderful job controlling the circus, and tamed the animals like a ring master. If the Karats stand against SC for Lok Sabha seat, they will loose their deposit. The people will always be more powerful than these arm chair communists.
