WASHINGTON (AP) — Running out of time and influence, President Bush faces a rough road in the twilight of his presidency regardless of who controls Congress.The once-unshakable loyalty of congressional Republicans is weakening. After marching in lockstep with the White House for six years, GOP lawmakers are looking at the political calendar and thinking about their own futures rather than Bush’s legacy in his last two years in office.

Republicans are in a sour mood, scarred by corruption scandals, held in low esteem by voters and divided over issues from deficit spending to immigration reform. Many GOP candidates shunned Bush in their campaigns, fearing he would hurt rather than help them.

With the end of the midterm elections and the opening of the 2008 presidential race, Republicans as well as Democrats will be telling the country how they would do things differently from Bush.

Already a huge headache, the Iraq war hangs over Bush as the dominant issue for the remainder of his presidency. Even before this year’s elections, Republican senators — from Virginia’s John Warner to Texas’ Kay Bailey Hutchison — were questioning Bush’s approach to Iraq, which this month will eclipse the Second World War in the length of US involvement. If Democrats should take the House or Senate, Bush’s problems would only get worse.

Shut out of power for a dozen years and bitter at Bush for ignoring them, Democrats would demand a role in setting the nation’s agenda and throw up roadblocks to the president’s plans. Pressuring Bush on Iraq, Democrats would have subpoena powers to investigate the president’s conduct of the war and to demand accountability.

The White House also could get snarled in Democratic-run investigations of issues ranging from Vice President Dick Cheney’s secret energy policy deliberations to White House links with Republican corruption scandals.

“It won’t be a happy place to work in the next couple of years,” said John Podesta, who has firsthand knowledge about running a White House in troubled times. He was Bill Clinton’s chief of staff during the tumultuous days of the Monica Lewinsky scandal and Clinton’s impeachment.

“Whereas you had a kind of lapdog Congress in the past, you’re going to have a significant challenge,” Podesta said of Bush. “Even if the Republicans retain control, you’ll see even more questioning on the Senate side.”

With Democrats in charge, there would be little chance that Bush’s prized tax cuts would be renewed. His drive to expand his executive authority and national security powers would be blocked.

Even with Republicans in control, Bush’s agenda has been stalled, his blueprints for overhauling Social Security and immigration collecting dust.

Time and history are not on his side.

“It seems like most presidents get less done in the last two years than they did in the earlier part of their term,” said Charles Black, a GOP strategist with close ties to the White House. “Some of it is you don’t have as much influence. People are paying attention to who might come next instead of who is there now.”

Before they leave, presidents sometimes try to shape their legacy with foreign policy victories. Clinton desperately sought a Middle East peace agreement in the closing days of his presidency but failed. The Middle East offers scant hope for Bush, too.

Trouble spots like North Korea and Iran look bleak. Bush insists he has a lot to do and isn’t slowing down. After the election, he plans to send Treasury Secretary Henry Paulson to Capitol Hill to see what’s possible in terms of overhauling the financially troubled Social Security and Medicare programmes.

“The general approach is to be activist and tackle big stuff,” White House press secretary Tony Snow said. “You’ve got a very energised and motivated White House. We’re going to see how Congress is in dealing with this. Maybe it’s just wishful thinking but we may be approaching the point of mudslinging burnout.”

Even if Democrats win, Bush still would have clout. As commander in chief, he is responsible for American forces. There isn’t much talk about Congress cutting off funds for war.

Probably the most potent weapon in Bush’s arsenal would be his veto pen and, almost certainly, a veto-sustaining minority if Democrats took the House. He also would have the power of executive orders allowing him to make big moves without Congress’ approval. Clinton used that authority, for example, to protect vast tracts of public land from road-building, logging and mining.
