re: I don't understand the Georgia poll results so far.

If you vote Warnock or abstain from voting, you have voted for Warnock. Warnock is the incumbent and the odds are pretty large that he will be re-elected because close to 100% are re-elected. If you are happy with Warnock then vote for him. If you’re not happy, but you don’t want to vote for Walker because he’s an idiot, then you’re saying that Warnock is your man. Not taking a side will give you Warnock.
