Former President Bill Clinton on Monday praised Senator Barack Obama's energy policy at the opening of the National Clean Energy Summit in Las Vegas.
But Mr. Clinton also lauded Mr. Obama's rival, Senator John McCain, and said that either candidate would be progressive on the issue of climate change.
"Obviously, I favor Senator Obama's energy positions, and Democrats have been by and large the more forward-leaning actors," Mr. Clinton said. "But John McCain has the best record of any Republican running for president on the energy issue and on climate change." He added, "I'm very encouraged about where the presidential rhetoric is in this campaign."
