Politicians throw around lots of terms, assuming the public just knows what they're talking about. The reality is that terms like "strict constructionism" and "astroturfing" aren't very clear cut. Some terms, like "socialism" are often widely misused by the general public, and even by some in the mainstream media and on Capitol Hill.
The following political terms are used frequently in conservative discussions, but the meanings behind them are often sketchy (at best). These definitions should help clear up any disputes.
Blue Dog Democrat
(in U.S. political discourse)
G-20 or Group of 20
