I have said many times in the past I don't choose to be vice president, either Republican, Democrat, Libertarian or vegetarian.

If the United States had not intervened in Afghanistan, then obviously, we would have then allowed the attacks of 9/11 to go unanswered. I don't think most of Americans wanted that to happen.

For decades we have been living lives of abundance, with little regard for our natural resources or global health. But we are now facing hard choices in our energy policy. Future generations - my children and grandchildren, along with yours - will have to live with the decisions we make today. And so it is time for us to make some tough and - hopefully - smart choices regarding our energy use and production before it is too late.

You know that old Beach Boys song, Bomb Iran? Bomb bomb bomb, bomb bomb Iran.

Immigration and border security remain critical issues that I am committed to addressing this year. The good news is that illegal immigration is at an all-time low, making now the time to dedicate the needed technology and resources to finally secure the border for good. As border security improves, I look forward to working in a bipartisan manner to fix our broken immigration system and address the millions of people living in the United States outside of legal status.

I do believe my view has evolved.
