The Tampa Bay Times is on the story as Marco Rubio becomes yet another ACA enrollee. Rubio used the D.C exchange and was able to use a federal subsidy which gave Rubio a 75% discount. Because you know, he could use that savings to buy a lot of water.
No doubt, Rubio must have had a great experience signing up for Obamacare. And let's also remember that any condition that causes extreme thirst like he saw Rubio have at his State of the Union rebuttal is covered under Obamacare and Rubio's policy could never be cancelled because of that.
The Tampa Bay Times also notes that Rubio may have even found a better deal had his home state Florida allowed an exchange.
