America is not a theocracy. In a free exercise nation, there is real danger in referencing God too much. Depending on the context, Bush may seem as deranged as Mullahs in Iran or Pat Robertson on TV. If W were conservative (rather than just claiming to be) and projected at least a marginal appearance of competence, his invocation of Almighty God wouldn't be so concerning.
The Bush's are killing the Republican Party. Bush 41 gave us Bill Clinton and a unified Dem gov't. They screwed up, fortunately, but now we're on the outside. It's going to be very hard to win the White House in 2008 but I want to win with someone who isn't crazy (McCain), two-faced (Mitt) or left of even W (Rudy)!
