As the Presidential candidates ponder potential running mates, a new Zogby International telephone poll shows many voters would be more inclined to vote for Democratic Sen. Barack Obama if he were to select retired four-star general and former Secretary of State Colin Powell as his running-mate.

If Obama were to choose Powell, 42% of likely voters nationwide said it would make them more likely to support the Democratic candidate - as did 42% of Democrats and 43% of political independents.

The Zogby International telephone poll of 1,039 likely voters nationwide was conducted July 9-13, 2008, and asked respondents how the selection of certain vice presidential candidates would affect their likelihood to vote for the two leading presidential candidates. It carries a margin of error of +/- 3.1 percentage points.

And what about the Obama/Hillary ticket?
