(CBS/AP)  Despite Thompson's remarks - and McCain's declaration that he was satisfied with the scrutiny his aides had given Palin before his selection - there were fresh disclosures.

Among them: that both as mayor of Wasilla, Alaska, and as governor, she had sought earmarks for local projects. Her most recent round of requests totaled $300 for every Alaskan. McCain has frequently vowed to veto any earmark legislation, and has said she will be a force in his battle to wipe them out.

Additionally, the lawyer hired to defend Palin in an ethics investigation said he also is representing her personally and is permitted to bill the state up to $95,000 for work in the current case. The issue involves the dismissal of public safety commissioner Walt Monegan after he refused to fire a state trooper who had divorced the governor's sister.

Republicans handed Lieberman the prime spot in the evening lineup, and he was set to blend praise for McCain with criticism of Obama.

"When others wanted to retreat in defeat from the field of battle, when Barack Obama was voting to cut off funding for our troops on the ground, John McCain had the courage to stand against the tide of public opinion," the Connecticut Democratic-turned-independent senator said in excerpts released in advance of his speech.

The decision to place Lieberman out front on the convention's second night capped an unprecedented political migration. Only eight years ago, he stood before a cheering throng at the Democratic National Convention in Los Angeles and accepted the nomination as Al Gore's running mate.

In the years since, he lost badly in 2004 when he sought the Democratic presidential nomination, lost a Democratic nomination for a new term at home in Connecticut in 2006, then recovered quickly to win re-election as an independent.

Back in the Senate, his vote allows the Democrats to command a narrow majority, yet he has been one of the most outspoken supporters of the war in Iraq. He has traveled widely with McCain in recent months, and occasionally has angered Democrats with remarks critical of Obama.

Mr. Bush, with his approval ratings in the 30-percent range, was relegated to a relatively minor role at the convention of a party that has twice nominated him to the White House. The president scrapped a planned Monday night speech because of the threat Hurricane Gustav posed to New Orleans. With polls making it clear the nation is ready for a change, the McCain campaign indicated there was no reason for him to make the trip to St. Paul.

One day after a frightening Gulf Coast hurricane prompted a subdued opening to the McCain convention, political combat enjoyed a resurgence.

McCain's aides disputed a claim that vice presidential running mate Sarah Palin had once been a member of a third party and accused Obama's camp of spreading false information.

Obama spokesman Bill Burton said that as far as he'd seen, "the only person talking about her being in the Alaska Independence Party is the head of the Alaska Independence Party."

"Their gripe is with those folks," he said of the McCain campaign.
