This combination of undated file photos shows U.S. Senate candidates Michigan Democratic Rep. Gary Peters, left, and former two-term GOP Michigan Secretary of State Terri Lynn Land. Thanks to the fiasco that followed the launch of President Barack Obama’s signature health care law, Democrats are now bracing for hard-fought Senate races in states they hoped to win with ease just two months ago. Weeks of technical problems with the health insurance enrollment website combined with anxiety over insurance cancellations for millions have erased early advantages enjoyed by Democratic candidates Peters in Michigan and Mark Udall in Colorado.
