In “House of Cards,” Underwood, played by Kevin Spacey, kills a passed-out congressman by leaving him in a running car in a garage, and pushes a journalist into the path of a subway train.

Imagining Spacey’s scheming character as president, 57 percent of respondents who have seen the Netflix political thriller said they held a favorable opinion of him.

Even Obama likes Underwood. “This guy’s getting a lot of stuff done,” Obama quipped during a December 2013 White House photo-op with Reed Hastings, Netflix’s chief executive.
