Candidates talk tough on economy as financial fears grow

Sen. Barack Obama tells Americans in a two-minute message that he is the candidate who can fix the financial crisis, while Sen. John McCain says in a new ad he's the one who will reform Wall Street.
The two candidates have been pushing their economic plans all week as voters deal with the failures of major investment banks on Wall Street and fears of a recession.
"This isn't just a string of bad luck. The truth is that while you've been living up to your responsibilities Washington has not. That's why we need change. Real change," Obama says in the ad, which begins airing Wednesday nationally and in battleground states.
Obama gives a brief overview of his economic plan and encourages voters to read it in detail.
"I approved this message because bitter, partisan fights and outworn ideas of the left and the right won't solve the problems we face today. But a new spirit of unity and shared responsibility will," he says.
After a week of being on the defensive, the economic crisis has given Obama an opportunity to go on offense. Most Americans see Obama as better equipped to handle the economy, polls show.
In McCain's new ad, he praises American workers as "the best in the world" and says, "Your economic security has been put at risk by the greed of Wall Street."
