The uninsured rate has dropped and stabilized during the first year of Obamacare's exchanges, according to new data from Gallup.

The trend is consistent with previous findings from Gallup and other polls, including the Commonwealth Fund, Robert Wood Johnson Foundation/Urban Institute, RAND Corporation and the Kaiser Family Foundation.

Gallup's Y-axis scale doesn't go all the way down to zero, which makes the drop look more dramatic than it really is. Still, the evidence is growing that Obamacare really has led to more people getting health insurance.
