Republicans Just Relaunched Their War on Obamacare. It Didn’t Go Well. Now that Republicans are in control of both chambers of Congress, the push to slay Obamacare by a thousand cuts is officially underway. But if the first stab is any indication, Republicans are going to need some sharper knives. *snip* For starters, there is the basic problem that President Obama has made clear that he’ll veto the 40-hour measure. If he does, Republicans could still seek to use the proposal as a cudgel to attack the law politically, but even here there are problems. The Congressional Budget Office has given the measure a decidedly unfavorable review. It estimates that the bill would result in as many as 1 million workers having their hours cut to put them under the new 40-hour limit and thereby losing their employer coverage; about 500,000 workers being left without any health coverage at all; and the deficit increasing by more than $50 billion as a result of fewer employers paying the $3,000 fine, as well as more people turning to Medicaid and federal subsidies to purchase their own insurance after being denied employer coverage.
