Just the Republican party.
The rules derived after Tucson are as follows:
1. Republicans/conservatives must be civil in the political discourse. Any violent imagery or military metaphors are banned, because deranged people such as the Tucson shooter hear this, and then go out and shoot somebody when they hear Republican rhetoric, or see Sarah Palin’s website which showed targets on certain Democrat congressional districts.
2. Democrats/liberals are allowed to say and do whatever the heck they want, because liberals are specifically exempt from the lessons of Tucson, and the rules derived after Tucson. A derange person would never be inspired by liberal rhetoric to go out and shoot somebody, because liberals are such peaceful people. When a liberal says something inflammatory, we all know these are figures of speech. When a conservative says something, it’s to be taken literally, which takes up back to rule # 1 above.
