Former New Hampshire Governor Reflects on Powell's Endorsement of Obama

Says it could be to do with race

An outspoken surrogate for Mitt Romney's White House campaign has suggested that race was a factor in former secretary of state Colin Powell's endorsement of President Barack Obama.

Former New Hampshire governor John Sununu told CNN late on Thursday that the re-endorsement of Obama by Powell - a Republican who served in both Bush presidencies but backed Obama in 2008 - was possibly due to both men being African-Americans.

"Frankly, when you take a look at Colin Powell you have to wonder whether that's an endorsement based on issues or whether he's got a slightly different reason for preferring President Obama," Sununu told CNN host Piers Morgan.
