From the February 3 Washington Post:

President Bush, forced by circumstance to reach out to some of his strongest adversaries, appealed directly to House Democrats on Saturday to work with him to reform the immigration system, limit the cost of Social Security, curb the consumption of gasoline and balance the federal budget.

Visiting the Democrats’ annual retreat for the first time since 2001, the president told lawmakers there are “big things” they could accomplish by working together and sought to defuse any bad blood with self-deprecating humor. He opened his public remarks with an allusion to his tendency to mispronounce the name of the rival party by calling it the Democrat Party, seen by many party activists as a
calculated insult.

“I appreciate you inviting the head of the Republic Party,” Bush said to laughter. He drew scattered applause a few moments later when he used the correct name in calling on the “Democratic Party” to work with him to address the mounting future liabilities of Social Security and Medicare.

Democrats rose to politely applaud Bush before and after the speech, a sign of the outwardly cordial and respectful nature of the day’s session.
