Where do the presidential frontrunners stand on these issues?

I was hoping someone could give me a some clear and concise answers on where John Edwards, Barack Obama, Hillary Clinton, Rudy Giuliani, and Mitt Romney stood on these issues that are important to me. 1) How do they feel about campaign finance reform, and lobbying reform. 2) What are their basic plans for the future of health care 3) Do they support gays and lesbians right to marry 4) Do they support military action in Iran

1. Can tell you that Hillary has made it clear she doesn't know what she is for in any case, (until she reads the polls, learned that from Bill). As for the rest, if those are your deciding issues, you have plans to move out of country? I smell hardcore liberal bed wetter here. Socialism at any price. Remember, your coming choice will be; convert to Islam or die, what's your choice?
2. Even if I could tell you how five different people feel about four different issues, I won't because it all makes my head hurt!
