Spacey was asked during an appearance on NBC's "Meet the Press" what Frank Underwood — the character he plays on "House of Cards" — would make of Trump.
Spacey said he's been asked before who would win in a debate between Underwood and Trump.
"I thought about this for quite some time and then I said as long as we understand that there is a distinction — that one of these figures is a fictional character … and the other is a fictional character. And I think as long as you understand that distinction," he said in response.
Spacey continued to compare the TV show to real politics, saying there are times after shooting a sequence when he'll ask himself if they pushed it "too far." 
"And then I turn on the news and I go, well, actually we probably haven’t gone far enough," he said.
After writing and shooting scenes for the show, oftentimes something very similar will happen in real-life politics, he said.
"We have decided on a storyline, we have written it, we have shot it and just before the series gets dropped, something very close to what we have decided to develop happens in real life," he said. 
"And I know people think we’ve ripped it from the headlines, but it’s actually the other way round. We think somehow they are getting our stories."
