Touring a Las Vegas manufacturing plant on Thursday, Gingrich tried to draw contrasts with Romney and Democratic President Barack Obama.
Gingrich said Romney and Obama think all the poor need is a safety net.
But the former House speaker said what the poor really need is a trampoline "so they can spring up."
Gingrich's comments were a clear jab at Romney, who said earlier this week that he is focused on helping the middle class because poor people have a safety net.
Gingrich was campaigning in Nevada ahead of Saturday's GOP caucuses there.
