The man who has led the effort to build the Barack Obama presidential library in Hawaii says Hawaii will be a top contender because there is nearly universal support for the library here from leaders across the state.  Robert Perkinson, a University of Hawaii professor, says Hono­lulu, with its location between East and West, is an ideal platform from which the former president can further his agenda.The Barack H. Obama Foundation this month (February) will ask parties seeking to host the library to make their interest known. Those who make the initial cut will submit formal proposals in May and the President and first lady will make the final decision, which will be announced in early 2015.
