U.S. Trade Representative Ron Kirk jabbed at Rick Perry's fading political fortunes as he traveled to Texas with President Obama on Tuesday.
"Too often the brightest stars are comets. But they flame out the fastest because they consume themselves on their own energy," Kirk, the former mayor of Dallas, told reporters on Air Force One en route to the city.
"I think there are some lessons to be learned there in life and in politics. How quickly and how brightly we burn," he said.
As Obama has traveled the country touting his jobs plan, it has not gone unnoticed how the White House has chosen settings loaded with political significance. Just weeks ago, he spoke in front of a decaying bridge that linked the home states of House Speaker John Boehner and Senate Republican Leader Mitch McConnell.
