“It’s a subtle change, notable only because it contributes to a reshaping of questions about the length of Mitt Romney’s tenure at Bain Capital, the private equity firm he founded,” the Boston Globe notes. “In recent days, Romney and his defenders have begun to say Romney left his “day-to-day” duties at Bain Capital when he took over the Salt Lake City Olympics in February 1999, seemingly absolving him of responsibility for any bankruptcies, layoffs or offshore outsourcing after 1999 by companies Bain had invested in.”

“An independent group supporting Mitt Romney raised a whopping $20 million last month, the most ever for a super PAC in a single month,” USA Today writes. “The fundraising haul by Restore Our Future dwarfs the $6.1 million raised in June by Priorities USA Action, the super PAC backing President Obama.”

Karl Rove thinks Romney should continue not to fight back: "They can't take the bait and fall into the mud with President Obama, because at the end of the day, if this is a battle between two mudslingers -- neither one of them looking presidential -- people will tend to go with the guy who is already president."

Newsweek looks at Sarah Palin not having been invited to the GOP convention in Tampa, and why that might be (bus tour stepping on Romney’s announcement, not fully embracing him, etc.)

In Las Vegas today, AFL-CIO chief Richard Trumka will unload on Romney, per excerpts of his remarks.  “[Romney] doesn’t care about hard work and responsibility. He doesn’t care that he created and ran a company that pioneered the practice of offshoring good jobs -- good union jobs -- to China and wherever else the labor is cheap. Mitt Romney doesn’t know a thing about responsibility. Hey, it was profitable for him to bleed companies, kill jobs, end pensions in bankruptcy court and then walk away with millions. What did he care? Maybe that’s fine for Mitt, but it doesn’t fly with me. It won’t fly with working families. And it won’t fly in the White House!”
