Washington, Aug 10 (ANI): Actor Leonardo DiCaprio doesn't seem impressed by 2008 U.S. Presidential elections hopefuls and is still not sure about campaigning for any candidate.

The Oscar-nominated actor, who staunchly advocated Democratic hopeful Senator John Kerry during 2004 elections, and even travelled across 14 states to support and raise funds for him, is not 'inspired' by the policies of any candidate this year.

"I'm still on the fence about it, to tell you the truth. I have yet to hear a candidate that has clearly laid out their environmental policy in a way that is inspiring to me," Contactmusic quoted DiCaprio as saying.

"I thought he (John Kerry) had an amazing environmental policy. But I have yet to hear a candidate that has compared in that regard," he said.

The 32-year-old insisted that he was still waiting for these candidates to raise important questions and take actions rather than play with words.

"I'm waiting for the right questions to be asked, and for these candidates to give really clear responses to what they're going to do in a tangible way - not a lot of rhetoric. I want to hear hardcore facts," he said. (ANI)
