Bob Dylan has claimed that Democratic US presidential nominee Barack Obama is "redefining politics".
The singer/songwriter said that he was hopeful that the political system in the US would change as a result of him winning the race to be the Democratic nominee for the election in November.
Dylan told The Times: "America is in a state of upheaval. Poverty is demoralising. You can't expect people to have the virtue of purity when they are poor.
"But we've got this guy out there now who is redefining the nature of politics from the ground up � Barack Obama. He's redefining what a politician is, so we'll have to see how things play out.
"Am I hopeful? Yes, I'm hopeful that things might change. Some things are going to have to."
