"...people currently have private plans through the ACA's government-sponsored markets. More than 8 in 10 receive subsidized premiums, and are cushioned from rate increases. Federal help paying premiums is still available despite GOP efforts to repeal the health law." [In fact, if they look at alternatives during open enrollment, they might get an even better deal.]
"... subsidies for premiums are also going up — by 45 percent on average. That means current customers receiving financial help have a strong incentive to renew."
"HealthCare.gov has new features intended to make it more user-friendly and the call center is fully staffed." [I called 800-318-2596 and a human answered right away, was helpful and said they are available 24/7.]
