Presidents talk a good game about improving the economy and helping business. But we end this week learning that President Obama has proven to be a one-man economic engine. Well, only if you’re a rude governor of a border state or a legendary soul singer.

Turns out, the now-infamous confrontation between Gov. Jan Brewer (R-Ariz.) and the president has done wonders for sales of her book “Scorpions for Breakfast.” According to, sales have gone up 200 percent over the last 24 hours. Last night, Brewer’s book ranked 21 in sales. It’s now No. 7.

Meanwhile, Al Green literally got a shout-out from Obama at the Apollo Theater in Harlem last week.

According to, Obama’s little soul-stirring performance of Green’s classic “Let’s Stay Together” resulted in “a 490% weekly sales increase for the song.” Amazing. If only the economy as a whole would respond as well to Obama’s boosting.
