Why not the “Kerry Rule”? He’s richer than Romney (thanks to Teresa) and only pays a 13% tax rate.

(WSJ) — As they say in politics, branding is everything.

Senate Democratic leaders suggested Wednesday that the so-called Buffett Rule should be renamed the Romney Rule, after GOP presidential hopeful Mitt Romneysaid this week that he paid less than 15% of his roughly $20 million in income in federal income taxes in 2010.

The proposal — dubbed the Buffett Rule by President Barack Obama — a nod to billionaire Warren Buffett who famously said his tax rate was a lot lower than his secretary’s, and that shouldn’t be — would require households earning more than $1 million to pay an effective federal tax rate of at least 30%.
