No, Bill Clinton is a leader and a man of integrity. There should be no comparison.
"A man of integrity"? The guy had an affair while in office and then lied about it under oath and Mitt Romney can't compare to him because of his integrity? 
Integrity is a wide term, not limited for private affairs.
Yeah, it means adherence to moral and ethical principles; soundness of moral character; honesty. And this is used to describe... Bill Clinton of all people. Really? Really? 
What goes on in a politician's personal life bears no relevance to me. And besides, Ken Starr's investigation of the scandal was far more unethical and deceptive than anything Clinton's ever said.
It may not matter to you, but it does to most Americans. This isn't France. What most foreigners (and quite a few American liberals, apparently) don't understand, is that in America, when you become a public official, your life instantly comes under greater scrutiny. You bear a greater responsibility to uphold your office in every aspect including your private life because we as citizens have higher expectations of you since you are representing us. How you conduct your private affairs reflect on your public role. There is no line of separation between the two. When you fall short, the consequences are that much greater.
