This week, the current federal-government shutdown will become the third-longest ever, surpassing a 2013 shutdown that lasted 16 days. There are some significant echoes of the 2013 shutdown, which stemmed from a failed Republican effort to "defund" Obamacare just as that health-reform initiative was being fully implemented. Now the shoe is on the other foot: Democrats are demanding that Obamacare subsidies, which were significantly expanded in 2021, be extended. Without congressional action, upwards of 20 million Americans will see a huge Obamacare premium hike at the end of the year.
