It may take weeks to render a verdict on the Obama administration's latest health care concession to employers. But that could make a difference for Democrats battling to keep control of the Senate in the fall congressional elections. All-important details are buried in more than 200 pages of dense Treasury regulations released Monday. The biggest change is that medium-sized firms got another delay in a heavily criticized requirement that they cover their workers or face fines. The administration said companies with 50 to 99 employees will have an additional year to comply, until January 1, 2016. For businesses with 100 or more employees, the so-called employer mandate will still take effect in 2015.
