I've noticed this too, to some extent. and I don't think its purely because of the President's party. TDS writers and Jon used to work hard to hold politicians feet to the fire no matter their party, and in the past few years I've seen them become increasingly outright liberal. Sure, that change happened around the same time as Obama, but I argue that the Daily Show of old would have been less coddling to the current administration.
