He’s already responded to the State of the Union, in anticipation. This, from a press release that just went out:

Governor Dean on the State of the Union
CONCORD–Democratic presidential candidate Governor Howard Dean, M.D., issued the following statement on President Bush’s State of the Union address tonight:
“George Bush’s empty proposals do nothing to address the real problems facing working Americans–problems his presidency has only made worse. On creating jobs, providing health care, and educating our children, I wish this President could learn from our example in Vermont, where we delivered real results for families.
“What will be most striking tonight is what this President won’t discuss: the three million jobs lost under his watch, the 43 million Americans without health insurance, the record level of bankruptcies, the $8 trillion increase in our nation‚s debt.
“The State of the Union may look rosy from the White House balcony or the suites of George Bush’s wealthiest donors. But hard-working Americans will see through this President’s effort to wrap his radical agenda with a compassionate ribbon.
“This week in New Hampshire, and as the campaign moves ahead, I look forward to debating with my opponents about who has stood up to George Bush on the issues that matter. About who has actually delivered results for people. About who has the experience and strength to bring real change for American families.”
