No idea who is most popular? Girija, Jhalanath, Prachanda, Baburam, Upendra Yadav all are popular in certain circles.

But, among all Baburam is the most hard working and honest person I guess. He is not a communist hardliner; can understand the need to change or give up some communist ideologies; lives a simple life, is not corrupt and has some vision of the future. He is not the perfect or best man, though.
