McCain's problems leave the distinct impression of being insurmountable. He struggles with a 'damaged Republic brand', an economy in turmoil and a country entrenched in unpopular wars. To make matters worse, questions have been raised about the ageing McCain's suitability. Even conservative Republicans like Bay Buchanan admit that the senator faces an 'uphill battle' against his charismatic opponent, Barack Obama. Meanwhile, even in the politician's home state of Arizona, an average voter dismisses McCain as merely 'part of Bush's plan'. Is there light at the end of the tunnel? Could McCain poach votes from disaffected ex-Hillary Clinton centrists? Former Democrats see the grizzled and experienced McCain as an alternative to the unknowable Obama.
