Appeals to people's fears of terrorism to convince lawmakers to renew the legislation.
Explanation:
In these lines, we see that President Bush uses an appeal to emotion (<em>pathos</em>) in order to convince people of his position. He tells us that the Patriot Act, which is meant to protect people from the dangers of terrorism, will expire soon. However, the threat of terrorism will not end at the same time. He implies that people will no longer be protected, and in this way, he appeals to their fear in order to approve the legislation.
