I find nothing new in these kind of statements from politicians. When Congress was in power, many BJP politicians were restless, including Modi ji who used to leave no chance to criticize one and all things Congress. Later, when BJP came in power, the same thing was seen with politicians of Congress and other parties. There is nothing new in it.
While such statements often have some valid points, but a politician's (no matter who) statement is never shot from mouth for any betterment of people. Mostly, it is their just another chance to get some limelight and win a few more hearts or followers. If the current Prime Minister was one from Lalu ji's party, such a statement may not have come. Likewise, if Lalu ji was in Modi ji's place and Modi ji in Lalu ji's place, even then a similar statement may have been released.
I do not wish to disrespect or offend any politician or their followers, but I find no difference in Modi ji and Lalu Prasad Yadav or any other politician. Many of these well-known faces seem to me as bloody selfish guys who are using their brains to win people strategically. If it is beneficial for them and their parties, they are so much able to find a mountain out of mole.
(Personally, I am a fan of Lalu ji for his funny statements and reactions that often go viral on WhatsApp. I don't know how bad or good he is as a politician, but he is an awesome entertainer.)
Also, despite of all the cat fight that keeps going on and on, I find Lalu ji's statement worth a thought. It surely has some weight...
