A growing number of insurers say they intend to offer coverage on the ObamaCare exchanges next year. Insurance plans in New Hampshire, Michigan and Illinois are planning to enter into the federal marketplaces after deciding not to participate during ObamaCare's first enrollment period, according to news reports. In New Hampshire, the number of ObamaCare insurers is set to rise from one to five next year; from 13 to 18 in Michigan; and from six to 10 in Illinois. The White House seized on the growing participation in ObamaCare to argue the law is succeeding.
