As the race for the 2016 U.S. Presidency heats up, President Barack Obama's controversial Affordable Care Act (aka, Obamacare) has been a hot topic -- particularly among Republican candidates. In this week's Fox Business News debate with the eight top Republican candidates, the topic came up numerous times.

"Obamacare has to be replaced because it's failing. It's failing the very people it was intended to help, but, also, it is crony-capitalism at its worst," said former Hewlett-Packard CEO and Republican Presidential candidate Carly Fiorina during Tuesday night's Republican debate in Milwaukee.

The states that have the fewest uninsured residents (meaning, people are signing up for insurance) happen to be mostly blue states, according to a WalletHub report.

WalletHub, in a new report, released on Tuesday, compared the uninsured rates pre- and post-Obamacare in each of the 50 states and the District of Columbia to provide a broad perspective of those rates as well as more granular analysis, such as, comparisons based on age, race/ethnicity, income and by private insurer vs. public insurer, by using U.S. Census Bureau data.

At the national level, the percentage of uninsured residents was 11.7% in 2017, down 3.8 points from 2010, WalletHub said, citing data from the U.S. Census' American Community Survey. 

The average rank for a "red" state, or those states whose residents vote primarily republican, is 34.54, while the average rank for a "blue" state, or those that vote primarily democrat, is 18.41 -- meaning that blue states have fewer uninsured residents than red states, according to WalletHub.

Here are the 10 states with the smallest proportion of uninsured residents.
