The facts about the Patriot Act blows this theory out of the water, just one question, who wrote the Patriot Act to begin with? And why did Bush support it?
The answer is in this Google search:
GOP did way more than support the PA.
They used it to win 2002 midterms. Any Dem who voted against it was marked and targeted('so and so is siding with the terrorists').
It was a convenient weapon to use at the time, but by 2006 the tables had turned on Republicans on the issue.
