House Democrats are blocking their Republican colleagues from using Obamacare in letters mailed on the taxpayer's dime to voters, but who made up the term in the first place? Lots of people are asking this question, getting answers like "Certainly a republican, potentially Glenn Beck" and "I am about 80% sure it was Rush Limbaugh" and "Hillary Clinton's campaign coined Obamacare." Iowa Rep. Steve King claimed President Obama himself made it up. Free Republic posters want to claim credit. Lots of liberals suspect an insidious plot by Fox News. But the answer appears to be: a lobbyist.
