I saw a poll out there
More than 90% of the Tea Party are also birthers
From watching the initial video of Trump on The View, Trump did not sound like a "born in Kenya" believer. His point was "WTF are you trying to hide, Obama? Release it, already!"
Afterwards, Trump has hit the Kenya button but I think he is just playing with Obama like a cat plays with a mouse. It's fun to watch. :-)
My opinion is that Obama was born in Hawaii but that the long form release would be very embarrasing for him by probably exposing him as a fraud that was born "Barry Dunham" ...... With a "Single" mother ..... Since polygamy is illegal in Hawaii.
