But now to Tampa, where this evening Mitt Romney will formally accept his party's nomination for president.
Last night, though, the stage belonged to vice presidential nominee Paul Ryan. In a campaign, it often falls to the running mate to be the attack dog and Ryan sounded up for the job. It was also a chance for the rising GOP star to defend his own ideas.

It is the wind that defines the strength of a hurricane. The storm is not a hurricane at all until the wind reaches 74 miles per hour. Hurricane Isaac's sustained winds were not much beyond that, so it was a Category 1 storm, not two, three, four or five. But if the winds define a hurricane, it's the water that can do the most damage.
Now, as Isaac moves north from Louisiana, it could affect other parts of the country, and we'll be following that story as it develops.
The other big story we have been following this week is the Republican National Convention in Tampa, Florida. Today is the final day, and it's an important one for GOP presidential nominee Mitt Romney. He'll officially accept the nomination this evening. Yesterday, Romney took a break from the hubbub of the convention to do a little campaigning elsewhere. NPR's Ari Shapiro reports on his getaway.
