Michael Barone and the Pew Research say that Evangelicals voted in approxmiately the same numbers they voted in 2000. Other groups had a higher percentage of new voters.
I respect Michael Barrone and the Pew Research Center, but that's simply not true. According to the actual exit polling data from 2000 and 2004, members of the so called "Religious Right" --- Christian Conservatives/Evangelicals/Born-Agains --- almost doubled their turnout in 2004 from 2000.
Just for the record.
In 2000, of the ~106 million Americans who voted, 14.84 million identified themselves as part of the Religious Right and 11.87 million voted for GWBush.
In 2004, of the ~118 million American who voted, 27.14 million identified themselves as members of the Religious Right and 21.16 million voted for PresBush.
I'd say the Religious Right was instrumental in reelecting PresBush.
