DETROIT -

It was a 6-minute speech that has some people still talking.

Former Michigan governor Jennifer Granholm's speech at the Democratic National Convention was nothing short of enthusiastic.

"And when American needed it most, who got us rolling again on the road to recovery? Barack Obama!" Granholm said in front of the cheering crowd. "America, let's rev our engines. In your car and on your ballot, the "D" is for drive forward, and the "R" is for reverse. And in this election, we're driving forward, not back."

Some have called the speech inspiring while others say it was crazy. Either way, Granholm is offering an explanation.

She told the Detroit Free Press that the crowd at the DNC got her energized when they cheered at the beginning. From there, Granholm said the delegates were so excited that she could not hear herself speak.
