Excerpt from the remarkable article (with embedded documentation) by Andrew Sullivan at The Daily Beast:
Below is a remarkable document. It’s a memo circulated by Jan van Lohuizen, a highly respected Republican pollster, (he polled for George W. Bush in 2004), to various leading Republican operatives, candidates and insiders. It’s on the fast-shifting poll data on marriage equality and gay rights in general, and how that should affect Republican policy and language. And the pollster’s conclusion is clear: if the GOP keeps up its current rhetoric and positions on gays and lesbians, it is in danger of marginalizing itself to irrelevance or worse.
