I assume you are a Democrat?
Nope. Video game censorship really isn't split by party line, if anything I imagine it is split by generational lines. Since no one in a generation that actually grew up with games is in power, it is hard to prove my claim though.

These video game bills are used to pander to the soccer mom\morality police voter base (which really transcend the traditional party split), much like sex offender bills. Since sex offenders and video gamers are an extreme minority of the voting public they can get away with this. The only solution is for gamers not to vote for anyone who supports awful bills like this. Sadly, this will never work as gamers just like to complain about these bills and will never, ever expend the effort to write their representatives or vote.
Okay, here is example.
This one from my home state of Illinois. It was the bill that would have placed huge annoying warning labels on games and banned the selling of "obscene and violent" games to minors, but you can read it yourself if you can stand all the awful legalese.
The bill passed the
Illinois House of Representatives 91-19 and the
Illinois Senate 52-5.
Of the 19 nays in the House, 5 were Democrats, and 14 were Republican.
Of the 5 nays in the Senate, 2 were Democrats, and 3 were Republican.
The bill was signed into law by a Democratic governor.
Interestingly, the Republicans had the most dissenters this time, although the bill still passed by a landslide in both houses. Thankfully, this bill was later ruled to be unconstitutional, although the appeal is still in the court system.
