The political climate will affect the market as a whole, while not a specific stock.
two political issues that will affect the market
1) presidential election - R is considered more business friendly by the market and will extend that bush tax cuts, will help the market by providing clarity, if D is elected I don't think we see a drop really but not a rally, market rallies when a new president takes office on hope
2) debt ceiling and deficit spending - the debt ceiling issue will be coming up again this fall, you know how it affected last time...problem with the debt issue is that even if the ceiling is raised, our debt is on the verge of becoming too much to ever pay back, if we don't see a turn around and a budget or plan to begin reducing the debt, even a little, in the next year or two, the market will definitely be affected
