* NEW: McCain says foes won't try to test him if he's president

MANCHESTER, New Hampshire (CNN) -- "Homeowners are the innocent bystanders in a drive-by shooting by Wall Street and Washington," Republican presidential candidate John McCain said Wednesday.
"It never should have happened," he said of the mortgage crisis that has shaken financial markets, and it would not have happened if he had been president, he said.
McCain defended his vote in favor of the government's $700 billion plan to prop up the lending industry, despite his insistence that as president he would cut spending.
"Extraordinary circumstances require extraordinary actions," he told CNN's Wolf Blitzer in Manchester, New Hampshire. The interview is to air on "The Situation Room" at 6 p.m. ET Wednesday.
McCain said he will consider a second economic stimulus package if he is elected president.
He attacked Barack Obama, his Democratic rival for the White House, for saying that "when you spread the wealth around, it's good for everybody."
That is "certainly not something I would ever do," he said.
Obama made the comment as he defended his proposal to raise taxes on couples earning more than $250,000 a year while cutting taxes for those with lower incomes. Obama says his plan would lead to lower taxes for 95 percent of American families.
McCain contended that Obama has been "all over the place" with his economic proposals.
And he said flatly, "I won't raise taxes on anybody."
He also vowed to "fix Social Security," refusing to rule out raising the retirement age or allowing some Social Security funds to be invested in the stock market.
He raised -- as he has for days -- a comment Obama's running mate, Sen. Joe Biden, made recently that if the Illinois senator becomes president, America's foes will manufacture a crisis to test him.
McCain said that will not happen if he wins the election.
"They know I have been tested. I have been tested many times," McCain said.
McCain discounted former Secretary of State Colin Powell's endorsement of Obama, saying that five former secretaries of state had endorsed McCain.
McCain said he is confident of victory November 4, though many polls show him trailing far behind Obama.
CNN's Poll of Polls showed him 9 points behind Obama nationally on Tuesday, with 7 percent of voters undecided.
