actually moudodi was the founder of JI.. nd majority of the muslims in pakistan dont like him nd even some of thm consider him a fasiq or shia due to his book "khilafat o maloqiat"...so personally i thnk ths is the only reason yet they fail to achieve any big success in politics.. nd i m sure whn they wil take a clear stance against moudodi .. JI will become the most popular jamat..
