A person nominally of the political left viewed as excessively critical of President Barack Obama, especially if the tendency is to reflexively or obsessively criticize him and seemingly not other political figures. Etymology: Jane Hamsher's popular, left-leaning FireDogLake blog was regarded by Democratic moderates as having gone around the bend in being hypercritical, such as when Hamsher appeared on Fox News to denounce Obama's Health Care Bill, got involved with Neocon
zealot Grover Norquist and even reportedly Tea Party activists. Thus, <b>FireDogLake + Teabagger
"Firebaggers are just pissed because Obama hasn’t invited them into the Whitehouse and/or isn’t the Great Liberal Savior they thought he was going to be (depending on the firebagger doing the bitching)."
NOTE: I tried several links to sources but links are rejected here; the term Firebagger can easily be googled
