(CNN) - As the president's re-election team starts showing more muscle on the campaign trail, Mitt Romney sharpened his attacks against President Barack Obama Tuesday, hitting his potential opponent as hypocritical and "disingenuous."
"He says things which are designed to solicit applause and affirmation, but in reality, he does very different things than what he's saying," Romney said on Sean Hannity's radio program.

The Republican front-runner particularly took aim at the president's speech earlier in the day at a media luncheon, in which Obama fiercely combated the recent budget plan put forward by House Republicans.
In his remarks, Obama outlined ways the GOP proposal, drawn up by House Budget Committee Chairman Paul Ryan, would make deep cuts in popular federal programs.
"It is thinly-veiled Social Darwinism," Obama said. "It is antithetical to our entire history as a land of opportunity and upward mobility for everyone who's willing to work for it."
And in a rare moment this early on in the campaign, the president also mentioned Romney by name and chided the candidate for supporting the plan.
But Romney fired back later in the day, saying Obama's efforts to rail against the budget proposal went too far in trying to drum up opposition for the bill.
"It's a disingenuous, fear-mongered approach, which I understand is going to catch a lot of attention," Romney said. "But if people dig a little deeper, I think they're going to understand that this is President Obama being President Obama, which is finding a way to deflect blame and to mischaracterize the efforts on the part of very thoughtful and serious minded individuals."
Romney also took the opportunity to paint the president as hypocritical, accusing Obama of repeatedly saying one thing and doing another while in the White House.
"It does seem to be a hide-and-seek campaign strategy, which is that he's going to hide what his real intentions are and he leaves it to us to try and seek them out," Romney said, mentioning Obama's 'hot mic' controversy with Russian President Dmitry Medvedev as an example.
Romney also pointed to the president's pledges to lower taxes and reduce regulation, as well as his calls for stricter trade relations with China.
"He says these things, but obviously he's hiding behind those words with policies that does exactly the opposite of that," Romney argued.
