It wasn't always this way. There were lots of honest Republicans when I was growing up, from Philadelphia's Thacher Longstreth, to Millicent Fenwick, to Gerald Ford. Now I can hardly think of a single one, with Bob Ehrlich (former governor of Maryland) being an exception.
Today's Republican party is home to the craziest, most extreme, lying lunatics ever assembled in one place.
To today's Republicans and creationists alike, the truth means absolutely nothing.
