On this week’s Slate Political Gabfest, David Plotz, Emily Bazelon, and John Dickerson discuss the fight over Romney’s Bain record and tax returns, the Republican veepstakes, and Yahoo’s Marissa Mayer.

Here are some of the links and references mentioned during this week's show:

• David references Jacob Weisberg’s comparison of Mitt and George Romney’s effective tax rates.
• John talks about an Obama ad running in Pennsylvania that wonders whether Romney paid any taxes at all.
• Emily’s favorite piece of veepstakes speculation was Nate Silver’s rundown of why each of the leading female contenders “would be at least a little risky.”
• The Gabfesters discuss an analysis by Slate’s Farhad Manjoo of Marissa Mayer’s new gig.
• Marissa Mayer doesn’t like to call herself a feminist? Well, “what part of ‘liberation for women’ is not for you?” Emily credits that question to British writer Caitlin Moran, who is profiled on DoubleX by Peggy Orenstein.     

Emily chatters a hypothesis: Three-ways are a movie plot device of the moment. The best movie she’s seen this summer is Your Sister’s Sister; David is disappointed her favorite wasn’t Magic Mike.

John chatters on McSweeney’s list of suggested Buzzfeed articles, and Buzzfeed’s capable reply.

Links Page Exclusive! David decides to not share his second chatter with John and Emily; he would have discussed a report that, for the first time, the average Canadian household is wealthier than their American counterpart.
