A Reuters/Ipsos online poll conducted in March asked Americans to rate various countries, organizations, and people based on how much of a threat they posed to the United States. Thirty-four percent of Republicans said that President Barack Obama was an imminent threat to the United States; only 25 percent said the same of Russian President Vladimir Putin.
Twenty-seven percent of Republicans consider the Democratic Party to be an imminent threat to the United States — the same number who labeled China as an imminent threat. Twenty-two percent of Democrats said the same of the GOP. However, nearly 10 percent of Republicans also think that the Republican Party poses an imminent threat to the United States.
