Carville and Greenberg urged Obama to hammer at Romney's plans to preserve income tax cuts for the wealthiest Americans while also cutting taxes on investment income that applies mainly to the rich.
Voters "are rightfully angry and increasingly populist," the two men said.
Troy agreed that Obama should risk being labeled too liberal if that's what it takes to defend his stimulus plan and auto industry bailout. Both initiatives generally got higher marks from economists than from average Americans.
The president can talk about the bailout "as a reflection of a government that is good, a government that works," Troy said.
He said the president should use Thursday's speech to "invite Americans back into the Obama narrative. He has to sell Brand Obama."
The president might skip many of the flourishes that wowed the crowd in Boston eight years ago. Instead, expect him to try to use the speech — one of the last remaining prime-time, heavily watched events of the campaign — to put the best possible face on a grim economy, and to convince voters that Romney would make it worse.
