Is the Better Person the Better Candidate?

A friend asked me to read "The Audacity of Hope", the book that expresses the deepest feelings for America as expressed by Senator Barack Obama.
My friend wrote that after reading this,it gave him a whole new perspective on Obama's candidacy,that a man like this deserved to lead our country. The mood I sense is that most folks think Hillary Clinton would back up a tractor on your grandma's withered leg to get what she wants,and that kind of open ambition makes some voters itchy. It is also why she would be a better candidate.
One of the reasons Bill Clinton won against Bush's dad (besides a stinky economy and a badly run campaign) was "Rapid Response", the practice of coming back fast and hard at any slur or negative output from the opponent. Hillary Clinton has raised this to a bare-knuckled art. When it comes to campaign toughened, who is the person more apt to fit that description? Yes,Senator Clinton.
What hasn't she been called? What slurs and mean spirited smears has she not been the recipient of? What public humiliation has she not endured?
Let me also say that I think that neither she or Senator Obama can lose to John McCain, given the war, the economy, and his doomed performances to come in the debates. I just don't want to take chances. I want the GOP out of the White House,so that real justices can occupy the Supreme Court, so that stem cell research can flourish,so that we won't have to be embarrassed to be Americans when we travel overseas.
Bless either one one of the candidates of the mule, but I need this win badly,and don't want to take a chance on another "decent but not tough enough" standard bearer.
