Washington ? President Bush warned Democratic critics of his Iraq policy on Tuesday to watch what they say or risk giving “comfort to our adversaries” and suffering at the ballot box in November. Democrats said Bush should take his own advice.

There are still 10 months left before congressional elections in which the president’s Republican Party could lose its dominance of Capitol Hill; a recent Associated Press-Ipsos poll found Americans prefer Democratic control over a continued GOP majority by 49 percent to 36 percent. But Bush is wasting no time engaging the battle. In his first speech of 2006 on the road, last week in Chicago, he aggressively challenged Democrats on the economy.

Tuesday’s equally sharp message represented an attempt by the president to neutralize Democrats’ ability to use Iraq – where violence is surging in the wake of December parliamentary elections and messy negotiations to form a new coalition government – as an election-year cudgel against Republicans.

Bush acknowledged deep differences over Iraq among casualty-weary Americans, just 39 percent of whom approve of his handling of the war, according to AP-Ipsos. Without specifically mentioning Democrats, the president urged campaigning politicians to “conduct this debate responsibly.”

He said he welcomed “honest critics” who question the way the war is being conducted and the “loyal opposition” that points out what is wrong with his administration’s approach.

But he termed irresponsible the “partisan critics who claim that we acted in Iraq because of oil or because of Israel or because we misled the American people,” as well as “defeatists who refuse to see that anything is right.”

Bush argued that irresponsible discussion harms the morale of troops overseas, emboldens the insurgents they are fighting and sets a bad example for Iraqis trying to establish a democratic government.

“In a free society, there’s only one check on political speech and that’s the judgment of the American people,” the president said to sustained applause from a friendly audience, a gathering of Veterans of Foreign Wars. “So I ask all Americans to hold their elected leaders to account and demand a debate that brings credit to our democracy, not comfort to our adversaries.”

Democrats said Bush has no business trying to define what sort of talk is acceptable.

“Patriotic Americans will continue to ask the tough questions because our brave men and women in Iraq, their families and the American people deserve to know that their leaders are being held accountable,” said Senate Minority Leader Harry Reid, D-Nev.
