Unions are finally acknowledging Obama broke his promise that “nothing in this plan will require you to change your coverage or your doctor"

Are unions really that dumb that they couldn't realize that Obama had clearly broken his promise earlier that “nothing in this plan will require you to change your coverage or your doctor"?  Some one needs to ask the unions why they didn't realize this problem until now?  Did they think that the Obama wasn't serious about what he wanted?  Or that Democrats would radically rewrite the law?  From The Hill newspaper:

Labor unions are breaking with President Obama on ObamaCare.
Months after the president’s reelection, a variety of unions are publicly balking at how the administration plans to implement the landmark law. They warn that unless there are changes, the results could be catastrophic.
The United Food and Commercial Workers International Union (UFCW) — a 1.3 million-member labor group that twice endorsed Obama for president — is very worried about how the reform law will affect its members’ healthcare plans. Last month, the president of the United Union of Roofers, Waterproofers and Allied Workers released a statement calling “for repeal or complete reform of the Affordable Care Act.”
UNITE HERE, a prominent hotel workers’ union, and the International Brotherhood of Teamsters are also pushing for changes.
In a new op-ed published in The Hill, UFCW President Joe Hansen homed in on the president’s speech at the 2009 AFL-CIO convention. Obama at the time said union members could keep their insurance under the law, but Hansen writes “that the president’s statement to labor in 2009 is simply not true for millions of workers.” . . .
