Former Vice President Dick Cheney is scheduled to speak in California to commemorate the centennial of President Ronald Reagan's birth.
His appearance Saturday night comes as conservatives are newly energized, after elections last year in which Republicans gained ground in Congress and in many statehouses around the county.
Cheney, who had broad influence in George W. Bush's White House, has heckled the Obama administration at many turns and has predicted President Barack Obama will be a one-term president.
The group sponsoring the event -- the conservative Young America's Foundation -- was founded to promote conservative ideas on college campuses and purchased Reagan's former ranch in 1998.
Sarah Palin addressed the group Friday.
