Daniel Henninger of the WSJ interviews Edwin Feulner, who founded the Heritage Foundation in 1974. The Heritage Foundation gained influence during the Reagan presidency. Feulner says he believes having the numbers right is important to maintain credibility, and it is important to respect the origin of the opposite side's ideas. Feulner reminds readers the Heritage Foundation has 600,000 donors as current members, and once turned down a check from textile magnate Milliken over its support for free trade. Its positions strive to be conservative, not Republican. Feulner looks ahead to political leaders like Jack Kemp who partnered with Bob Garcia of the Bronx on urban revival, and could take caring positions outside the political spectrum.
