The difference between a liberal and a leftist

The easiest way to tell the difference between a liberal and a leftist is that a liberal cheers against his country only when a Republican is in the White House, while a leftist cheers against his country all of the time

writes Benjamin Duffy of the University of Massachusetts.

Simply change the party in power, and liberals will change their minds on just about everything. Leftists on the other hand, are a lot more consistent. They're consistently wrong, venomous, anti-American and misguided, but at least they're consistent.
