what is the wrong and irresponsible answer by a Congress Chief Minister made an end to Congress Rule at Tamil nadu ?

Today in a press ,media questions in sun TV Mr. E,V,K,S,Elangovan not answered in a Normal manner  he used to be.

Let me tell the Question by SUN TV Anchor .
Why Kamaraj could not able to establish Congress Rule in Tamil Nadu after 1967?

My View and answer to this question is :
1.
Mr.Kamaraj was deceived by Mrs.Indira Gandhi is a well Known Matter.
2.
In 1967 in a Public Meeting the respond to people by the than Congress Chief Minister Late Mr.Bakthavatchalam was went wrong , and it was the prime Reason How D M K lead By Mr.C.N.Anna Durai could catch the Power in Tamil nadu!.
3.
What is the Reply/respond by the than late Chief Minister Mr.Bakthavatchalam was , while people shown angrily the Poor Quality of Rice with worms supplied at Ration Shops to the chief Minister Late Mr.Bakthavatchalam , the following reply late Mr.Bakthavatchalam said to People, that is ,Put Hot water in Rice and all worms will die and float on the top of the Hot water than once again put fresh hot water in to that rice to cook it.
This is the wrong and irresponsible answer by a Congress Chief Minister made an end to Congress Rule at Tamil nadu ?..

He could have told that because of severe famine,Severe water shortage ,cultivation was restricted and their by No Rice stock available, even though we will take action to import and replace the quality rice supply at Ration shops shortly ,must be a good answer is my Opinion/view/recommendation. 

4.
In this Rajaji worked in favor of D M K and he did not supported to Congress.

5. Congress and its leaders  last its confidence in people of Tamil Nadu than they started join hands with Either D.M.K. or A.I.A.D.M.K. in General elections is a wrong Move. Than it has become a slave practice to it.

6. The Only Leader had courage in facing people from Congress was Late Mr.G.K.Moopanar. who told and focused Pressure on All India National Congress Party Leader that Congress must not ride on others and this idea must come to an end.After the death of a Political Giant Late Mr.M.G.R. G.K.Moopanar had interest to promote Congress to its original shape is also true.
But it was not properly responded,so Late Mr.G.K.Moopanar started its own Political Party called T M C with Cycle Logo contested in Elections. after his death/demise Once again Congress leaders like K.V.Thanga Balu started congress ride on  D.M.K. or A.I.A.D.M.K. Banners. Congress believed that it can ruin these parties by joining hands with them is also an ideology.

7. On Date D.M.K. Last its Values in people because of its interest on LTTE of Sri Lanka is also True.

8. Now D.M.K. depends /looking for D M D K ,P M K , V.C., and M D M K. all join together can not frame a Pressure on A.I.A.D.M.K. is also True. But Congress and B J P as National Parties Must contest individually in all 535 Constituencies will add  values to Democacy is also True.
 9.
In Tamil Nadu  doing Politics between Dravidian Parties is not existing. Both parties working  on separate    Tracks and ideology. Present Politics  totally differs and it is not like Politics lead by Mr.M.G.R. and Mr.Karunanidhi.of that time in Good Under standing is also true?.
Thanks.
