Romney and the VP

If you had a major announcement to make that no matter what else happened in the world that week would still be a headline story, does the timing really matter?
I guess it might a little bit, just so you don't have to share the headlines, and you can get the most mileage out of it. But if you were going to do that, you would have to be 100% confident in your announcement. Because if you weren't confident in it, you might choose to do something like announce it on a Friday afternoon, during a busy news week, and as a result, getting little traction.
Which is why I predict Romney will make his VP announcement next Wednesday. Maybe Tuesday or Thursday. But Wednesday gives you two full days of headlines, plus the weekend talk shows.
The Olympics will be less exciting by then (but still underway), and the Aurora shooting stories will have quieted. Without any other obvious competition, that seems like a good time to announce. Assuming he's made his decision that is.
Not to mention, the campaign has planned out a big swing state tour in the upcoming weeks. Sure maybe it is just another stump speech tour. But you'd have to be a complete neophyte to believe that he would go on a big tour 2 weeks before the convention, without a VP at his side. 
The big tour begins August 10, and is rumored to go through Virginia, North Carolina, and into Florida. He's also supposed to be showing up in Indiana, Ohio, and Colorado. 95 electoral votes between them.
Who might the VP be? Someone completely groomed and well-vetted? (Bob McDonnell, Rob Portman, Chris Christie, Tim Pawlenty) Or someone who brings a key swing state (Rob Portman, Tim Pawlenty, Marco Rubio)? Or someone who jazzes up the ticket? (Bobby Jindal, Nikki Haley, Marco Rubio)
I have my personal choice, but I want to hear other people's preferences. Who do you want it to be? Who do you think it will be?
