Warren Buffett’s claim that he pays a lower tax rate than his secretary inspired an SOTU guest. (Tomohiro Ohsumi/BLOOMBERG)

But the prospect of sitting with first lady Michelle Obama at tonight’s State of the Union address apparently is something different altogether. Bosanek, who’s mostly kept an under-the-radar profile despite being the poster lady for President Obama’s tax proposals, tells us she’s a tad jittery.

“I was so excited I couldn’t sleep last night,” she says.

Bosanek will likely be a hot topic in tonight’s speech: President Obama is expected to highlight his proposed “Buffett Rule,” which he said was inspired by the billionaire investor’s oft-repeated statement that he pays a lower tax rate than that of his secretary

But even though this might be her first SOTU rodeo, she’s apparently got a pro’s instincts: she’s planning to wear a red jacket--red being the favored color of many a veteran attendee. After all, the bold hue stands out amid the sea of dark suits (and robes, in the case of the Supreme Court justices), plus it looks great on television.

But Cinderella-like, after the brief turn in the Washington spotlight is over, Bosanek plans to catch a crack-of-dawn flight back to Omaha, where the low-key headquarters of Buffett’s Berkshire Hathaway, Inc. are located.

After all, the boss is waiting.
