A series of Congress ministers have attacked the BJP's prime ministerial candidate, Narendra Modi, but the party's vice-president Rahul Gandhi has not joined them. Why haven't his campaign speeches offered a direct counter-argument to Mr Modi? Speaking to NDTV, union minister Jairam Ramesh, who is the Congress convenor of the Lok Sabha elections, said that he believes that Mr Gandhi should not get into "a tu tu main main" with Mr. Modi, who he accused of subscribing to the "politics of the gutter...of invective and abuse."
