He also claimed that many NCP MLAs would vote for him.
"We should not be limited to the fact that he is a tribal candidate, what is more important is to see his contribution to the offices that he held (as Speaker and Union Minister)," Conrad, who is Sangma's son said.
He said his father has a clean image all through.
He said it would be a matter of pride and things would be different for the people of the region if he becomes the President.
"It is sad that people do not see that aspect and happiness....It is sad to see that people are taking it with such a negative manner," he said.
Conrad claimed that the party (NCP) high command would not be issuing any whip and hence the elected leaders of the party can vote for Sangma.
"I am voting for P A Sangma. MLAs in Manipur, Arunachal Pradesh, Kerala and Odisha are supporting him," Conrad claimed, adding that about 10-15 per cent NCP elected leaders are openly supporting him.
The young NCP leader hoped every voter from NE, every tribal and every Christian will vote for Sangma.
On the campaign undertaken by Sangma, Conrad said every candidate for the Presidential post should campaign so that the post is not reduced to a rubber stamp one.
The Meghalaya Leader of Opposition, however, expressed unhappiness over Assam Chief Minister Tarun Gogoi's open statement against Sangma.
"It was sad to see Gogoi react that way... I think he acted on a party line and to keep Sonia Gandhi happy," he said.
Gogoi had said, "Be it Congress or non-Congress, no one has lent any support to Sangma. Even his own party is not supporting him. I have never seen anyone himself canvassing for the President's post."
