WASHINGTON (AP) - Relishing the prospects of a triumph, Democratic leader Nancy Pelosi yesterday promised to restore integrity and civility to the House if voters put her party in control this fall.

"We'll turn the most closed and corrupt Congress into the most open and honest Congress," Pelosi (D-Calif.) told The Associated Press in an interview.

She spoke five weeks before the midterm elections as the House ethics committee opened an investigation into an unfolding sex scandal that led to Rep. Mark Foley's resignation and calls for House Speaker Dennis Hastert (R-Ill.) to step down.

"The only way you can make the change that needs to be made for our country - a new direction where we're there for the many and not the few - is to drain the swamp," said Pelosi, who is in line to be the nation's first female House speaker if Democrats ascend to power.

With Nov. 7 looming, an AP-Ipsos poll released yesterday found the majority of likely voters favoring Democrats to win control of the House and half of likely voters saying recent disclosures of corruption and scandal in Congress will be very or extremely important when they cast their vote.

Republicans are scrambling to try to stop the political bleeding that began last week when Foley resigned amid reports that he sent sexually explicit communications to teenage boys who once worked as House pages. That set off finger-pointing among House Republican leaders who were accused of failing to react quickly when they were warned of Foley's behavior.

Hastert spurned calls for his resignation from the party's conservative base while some Republicans expressed fears that the scandal could cost the GOP the House.

In Idaho, Republican Rep. Mike Simpson said he was no longer confident that Republicans would retain power, a shift from a week ago when he was "fairly confident we were going to keep the majority." Now, he said, it's "a real tossup."

Republicans outside of Washington, meanwhile, chastised Democrats for criticizing House leaders while ignoring what Republicans called a long and tawdry history of Democratic impropriety and sex scandals.

"What we don't have to do is allow our friends on the left to lecture us on morality," former House Speaker Newt Gingrich (R-Ga.) said at a party fundraiser in South Carolina. "There's a certain stench of hypocrisy."

On Capitol Hill, Pelosi expressed confidence that Democrats would gain the 15 seats they need to seize control of the House from Republicans who have ruled for a dozen years.

Should Democrats win, she promised they would approve rules to "break the link between lobbyists and legislation" and enact legislation adopting all the recommendations of the bipartisan commission that investigated the Sept. 11, 2001 terrorist attacks. The party's agenda also includes raising the minimum wage to $7.25 an hour and cutting the student loan interest rate.
