Barack Obama can stand four more weeks of John McCain's attacks but America can not stand four more years of President George Bush's failed policies, the Democratic presidential candidate said today. Mr Obama linked his Republican rival to the unpopular president as he returned to the campaign trail in the battleground state of Indiana after performing well in the second presidential debate last night. The McCain campaign has said it intends to ``turn a page on this financial crisis'' and divert attention from the candidate's stumbling response which has damaged his presidential bid by ``discussing Mr Obama's aggressively liberal record and how he will be too risky for Americans''. Mr Obama said Mr McCain and his running mate Sarah Palin were ``out there saying all kinds of stuff''. He went on: ``And McCain's campaign actually said, and I quote, I'm quoting here, 'If we keep talking about the economy, we're going to lose'. ``Well I've got news for John McCain, this isn't about losing a campaign, it's about Americans who are losing their jobs, Americans who are losing their homes, Americans who are losing their life savings. ``I can take four more weeks of John McCain's attacks but the American people can't take four more years of John McCain's Bush policies.'' With just four weeks to go until the election, Mr Obama leads in virtually all the battleground states and has more than a five point lead nationally in the latest average of polls by Mr McCain's poll numbers plummeted as his campaign stumbled in its handling of the financial crisis engulfing the nation in recent weeks. Mr Obama said it was the ``final verdict on the failed economic policies of the past eight years'' as he linked Mr McCain's candidacy to the presidency of Mr Bush.
