Are Congressional Republicans that ashamed of the Constitution?

In response to legislation curtailing the warrantless wiretapping and other illegal surveillance techniques used by President Bush's administration, many Congressional Republicans have expressed dismay:

The measure "extends our Constitution beyond American soil to our enemies who want to cut the heads off Americans," said Rep. Louie Gohmert (R-Tex.).

I thought that Iraq represented an opportunity to spread democracy and American political values beyond our borders. So why would we be ashamed to extend our Constitution - the enumeration of our values - beyond American soil?
