How would you flush a KGB mole out of the Democratic Party? It isn't looking for a needle in a haystack. It would be looking for a bit of hay in a haystack.
Seriously, what would a KGB mole do? Get the Democrats to push for stealth socialism? The Pubbies do that half the time. Get the Democrats to sow defeatism? Pat Buchanan does that every time.

Well, KGB would refer to actual espionage activity, as opposed to pushing socialistic public policies, and I suppose they could still engage in espionage activity (though it'd be cheaper for them to just read the NYT). . .but your point is taken. A friend from France who moved here once told me that he could see no significant difference between the French socialists' policies and the Democrats' policies, the only difference was that the Democrats didn't call themselves "socialists".
