SACRAMENTO -- Taking center stage at the Democratic National Convention this week is a Sacramento man who never expected to be there.
"I start out the speech by talking about how it's a little bit of a shock to be with all of them because they're all Democrats and I'm a Republican," said Doug Elmets.
Elmets worked for Ronald Reagan's presidential campaign and in his White House.
He was asked to speak about why he believes Donald Trump shouldn't be president.
"It's not really about me, it's about those who believe that Donald Trump is a petulant unbalanced reality TV star who doesn't deserve to be president of the U.S.," Elmets said.
Hillary Clinton does deserve it, says Elmets.
"I believe that Hillary Clinton is the best prepared to be president in modern times," Elmets said.
"I mean its all over the media how she lies and she's deceiving," said Trump supporter Rich Mendoza.
Some Trump supporters from Stockton can't understand why any Republican would vote for Clinton.
"Supporting Hillary? You gotta be nuts!" said William Douglas.
They insist Trump is the only hope for America.
"He's out there, but I think that's what we need. I think this country is too politically correct," said Mendoza.
Thursday Elmets will speak before millions of people about the importance of voting for his country versus his political party, the differences between Trump and Reagan and why for the first time, a Democrat has earned his vote.
"Donald Trump has hijacked the Republican Party and it is no longer the Republican Party it has turned into the 'Party of Trump'," said Elmets.
Elmets will speak Thursday night before Hillary Clinton officially accepts the nomination.
