A question for Kejariwal

I just don't understand... how we follow the wind blindly .... Jai Prakash Narayan... who was the leader behind many thoughts...a leader of RJD and mentor of many political parties.... if his party can go wrong.. and give the leader like Lalu and others... what is the gaurantee that Kejariwal for whom we are putting everything.... even we are giving the chance to kejriwal or as spoiler he can make congress again in Delhi... what we will get from him.... 20 years we will make to strengthen him.. and post that we will realize we got one more Lalu... Then why not strengthen a Party which is much shaped than other existing one... And clear the dirt from BJP to make it a better alternative. Because this is always benfit congress.... As we give our strength to many scattered good ppl... who can not come togather...eve
