" Dems supported Bush in the run-up to the Iraq war...."

1) Some did, some didn't.

2) We've discussed this ad nauseam already--the Bush regime ran a masterful propaganda campaign--in fact 2, one to persuade the US public to support the Iraq warm, and a second to win the 2004 election--"watch out for homosexuals and terrorists.   Here in (your city's name here) a dirty bomb could be exploded. And if homosexuals can call themselves married, YOUR marriage is in danger."

As several of us have said before, it was all about hate and fear.   And in a fearful country, it works like a charm.

Until people start thinking. Which it appears they have.
