On their website -
http://www.gop.com/, it's the more politically correct "happy holidays".
...but the banner above the emailed greetings from Ken Mehlman say "Merry Christmas"
As we celebrate the holidays, I wish you a Merry Christmas, Happy Hanukah, and Happy New Year from all of us at the Republican National Committee. We hope the spirit of Christmas remains with all of us throughout 2006.
We are especially grateful to the men and women who serve this country so courageously overseas. These American heroes, far from home, are fighting the enemies of freedom and keeping our country safe at home. We recognize their sacrifice as they help win the War on Terror. We hope they know how proud we are of them.
During the holiday season we take the time to reflect on an historic year of accomplishment. The strength of our cause is built on the dedication of each and every Republican across this country, and we look forward to another great year ahead. May the joy of the season bring you renewed happiness on this day and everyday throughout the New Year.
Merry Christmas!
Ken Mehlman
Chairman, Republican National Committee
