WINTER PARK, Fla. -

President Barack Obama is accusing Republican rival Mitt Romney of promoting "trickle-down tax cut fairy dust" that he says would take the nation in the wrong direction.

Campaigning Thursday in Rollins College in Winter Park, Fla., Obama tqackled Romney's economic plan for the second straight day, telling supporters that it would give tax cuts to the wealthy at the expense of more modest earners.

The president again pointed to an outside group's report that concluded that Romney's plan would force many Americans to give up popular tax deductions and shift the tax burden from wealthy to low- and middle-class taxpayers.

Obama says Republicans have pushed tax cuts before. He says, quote, it "didn't work then and it won't work now."

Campaigning in Golden, Colo., Romney promised that his economic program will create 12 million new jobs in the next four years, and likened President Barack Obama to a "dog trying to chase its tail" when it comes to strengthening the sluggish recovery.

The two men campaigned in battleground states hundreds of miles apart, both on a mission to convert undecided voters to their side in a race dominated by the economy.
