To tampa, where the gop convention is back on track. It's "your voice, your vote" with abc's jonathan karl. And the roll call to officially nominate mitt romney is this afternoon. All speeches set to go tonight. But a wary eye on isaac. Reporter: Officials are watching as isaac heads towards new orleans. What they're worried about is the image of it slamming the gulf coast, as they have a big celebration here. Technically, the convention has already started. It's my privilege to proclaim the 2012 republican national convention in session and called to order. Reporter: The first session lasted just 32 seconds. Long enough to take the first swipe at president obama. We also want to draw your attention to the unprecedented fiscal recklessness of the obama ADMINISTRATION. Reporter: The storm didn't delay the protesters. They managed to briefly block all traffic around the convention site. Paul ryan made one last campaign stop before heading to tampa to accept the vice presidential nomination. A homecoming visit to his native janesville, wisconsin. Hello, janesville. It's good to be home. Reporter: The 40-year-old ryan told fox news he's not too young for the job. I have more experience than president obama did coming into office. Reporter: In new hampshire, both romneys prepared for their convention speeches. I like my speech. I like ann's speech. Repter: Ann romney speaks tonight, so does keynoter chris christie. There's no excuses. It's time to get to work, everybody. Time to get to work. Reporter: The storm isn't slowing down the obama campaign, either. In fact, the president heads to iowa today to kick off a two-day campaign swing.
