Therefore, I am biased in favor of McCain, but why? Here is a list of a few issues I care about, where the candidates stand and where I stand. In fact, I am not so much biased toward McCain, as I am biased toward anyone who shares my values and convictions. So if Obama wants to convert to what I hold dear and near, I'd gladly endorse him. As you can see, he's not very close to center and as McCain says; "it's hard to reach that far across the aisle."
Abortion: McCain against (considers life to begin at conception). Obama for (in an extreme way). I am against abortion (see previous post). In my opinion abortion is at best an extreme, violent act that reveals a person's worldview and permeates his thinking and perspective. Therefore, I have trouble trusting or voting for a person who supports abortion.
Here are a few more related issues with which I happen to side 100% with McCain (Also see this previous post). From Value Voters USA:

Gay Marriage: McCain against. Obama for. I don't believe the age-old definition of "marriage" should be tampered with. Gays already have legal rights that are equivalent to marriage - just call it something else. I don't believe gays really want to get married anyway since only about 2% have gotten married in countries that have made it legal; instead they desire their choices and beliefs to become mainstream.
Commander in Chief: McCain is experienced and I do not believe he is war/trigger happy but instead has a proper understanding of the costs of freedom and the role of government versus the individual when applied to protecting a people. Obama is not seasoned, experienced or mature in foreign policy and I believe will be tested, and the cause of the testing, as JFK was with the Cuban Missile Crisis. I believe Obama has a wrong perspective on America's place and responsibility in this world (another post to come). I don't care if the rest of the world and the U.N. disagree with America's choices, because doing what's right is not about being popular. Obama can be a citizen of the world if he wants to, but I do not believe the world has America's best interests in mind and our next president should not be swayed by world opinion. I think it's a shame that the intent of America's founding fathers is so often rejected when that solid foundation is the reason America has been so great. If you want to experiment with what doesn't work, move to Europe.
Unions: I don't know where McCain stands, but I'm not a big fan, especially when they give a percentage of my dues to charities I don't approve of such as Planned Parenthood. I do however strongly disagree with the power Obama wants to give unions.
There are issues that I'm not as opinionated on and which aren't as big a factor in deciding who I would vote for. Some issues where I'm not as decided on or as educated on are immigration, health, social security, trade, housing, economy and certain bailout plan details, although I always lean toward smaller government if possible and against socialist policies. There is a place for taxes and "giving unto Caesar" and there is a need for welfare and infrastructure and military. However, in our current economic downturn, why raise anybody's taxes until the recession turns around? Let's get rid of the corruption and waste first. Let's get rid of some of those deadbeat government employees that are so hard to fire. Let's enforce existing tax laws.
One issue where I'm against both candidates is stem cell research. I approve of research with stem cells. I disapprove of research with embrionic stem cells. I'm bugged when the two aren't differentiated. Again, this is my value of supporting a "culture of life." There is great hope for non-embrionic stem cells and it is unjustifiable and unnecessary to create a life to destroy it.
I disagree with both candidates on Global Warming, but that's another post coming as well.
Here's a good source on the platforms of the candidates.; from The Boston Globe.
