Elton John may have seemed like the last person expected to perform at Rush Limbaugh’s wedding over the weekend.
Limbaugh, 59, has made a number of colorful remarks about gays that have sparked outrage – and kept his conservative credentials intact. But on some issues, they do share common ground.
Limbaugh, for instance, told Zev Chafetz, author of the Limbaugh biography Army of One, that he supports civil unions for gay couples instead of marriage – a point on which Limbaugh and the openly gay John agree.
