However, this card really shines in common ground games, where you don't have a lot of high tech cards anyway, so drawing extra cards tends to be more useful. Besides, in CG, he's one of the few native 2 influence voters.

EDIT: I've changed my mind a little bit with this card. First off, one usually doesn't need extra cards (Avid Raiders) until a little later in the game. Coalition Senator works everywhere, not just at the Star Chamber, so later in the game, when you might want to draw more cards, Coalition Senator makes every conquerer an Avid Raiders. His ability stacks and he has voting influence. Ditch one to place a flag if you already have one in play, means you get a free card, or as an alternate choice if your opponent is ignoring the Chamber. I upgraded him to decent, if he's in the right deck. (If it were only for his card drawing ability, though, I'd go with Gifts.)
