Near term partisan pressure on the market? (stock)

Maybe I'm thinking too much into this, or maybe I'm just overgeneralizing too much. Yesterday the stimulus bill went through in the House vote without a single GOP vote. I'm going to make a big assumption here and say that the majority of big market participants are republicans. Wouldn't these people feel much less confident about the immediate future of the market if their representatives can be waved aside on a bill this big?
