Indiana Republicans are on the verge of passing a plan that might just be enough to push the three-term Democrat into the state's Senate race. Under the initial legislative proposal, Donnelly's 2nd Congressional District would lose blue-collar Michigan City and Kokomo (which provided him his 2010 margin of victory) and pick up rural Elkhart and Kosciusko counties, two of the most conservative pockets of northern Indiana. Under the new lines, President Obama's 2008 share of the vote in the district would fall from 54 percent to 49 percent.
