Yes, Novak is a registered Democrat. That is because he lives in DC and there is no GOP in DC. The only way he has any input in local politics is by voting for the least crazy of the Dems in the primaries.
This fact is widely known and those who quickly point out that Novak is a Dem have been told the reason many times all ready but they continue to pop on to every Novak thread to "shoot the messenger" with the "he's a Democrat" ammo. It is strictly a tactic to keep conservative readers from considering what the man reports.
cordially,
