A wonder in kerala politics

Some times i wonder about cpm state secretary Mr.pinarayi vijayan.he is not a good speaker.his speeches are very cold.which fails to encourage anyone.there are no depth in his speeches.some times he even use some dirty collaqial language in his speeches.still he is the leader of cpm in kerala with lot of followers.i do not know the secret behind this.may be he is having some sort of charisma  which i fails to understand.whatsoever i wish him all the best in his political career.
