Former Secretary of State Colin Powell may have voted for President Barack Obama in 2008, but that doesn't mean he's backing him for reelection in 2012.

I haven't decided who I'm going to vote for, said Powell on CBS's Face the Nation. Just as was the case in 2008, I am going to watch the campaign unfold. In the course of my life I have voted for Democrats, I have voted for Republicans, I have changed from one four-year cycle to another.

Looks for Best-Qualified Person

I've always felt it my responsibility as a citizen to take a look at the issues, examine the candidates, and pick the person that I think is best qualified for the office of the president in that year. And not just solely on the basis of party affiliation, said Powell.

When asked about the current crop of Republican candidates, Powell said there are some interesting candidates, but no one who has emerged into the leading position, ABC News reported. So let's see if anybody else is going to join, and we've got a long way to go.

In 2008, Powell, the country's first African-American secretary of state, praised Obama for his leadership style, saying, Obama has a definite way of doing business that will serve us well.
