(CNN) — This may be President Obama's time, but it's still Ronald Reagan's era.
Obama has helped negotiate a nuclear deal with Iran, normalized relations with Cuba, and watched his approval ratings recently hit a two-year high after the U.S. Supreme Court upheld Obamacare. But has he become a "transformational" president like Ronald Reagan?
"He's simply plowing the ground Reagan cleared 30 years ago," says Tom Nichols, a political blogger and author of a column "Fantasyland: Obama Is No Ronald Reagan," referring to Obama's policies on nuclear weapons and his agreement with Iran.

The Obama-Reagan comparisons are nothing new. Obama first made the comparison himself years ago when he declared that Reagan "changed the trajectory of America" and "put us on a fundamentally different path."
But we took the comparison a step further. We asked a group of historians and political scientists from the left and right to describe the qualities that make a president transformational. We also asked whether Obama lines up more favorably against Reagan now that he's reached a deal with Iran.
