Mike Braun, the Republican candidate for a crucial Senate seat in Indiana, often refers to his rival, Sen. Joe Donnelly, as "Sleepin' Joe" and has vowed to wake the vulnerable Democrat from his "siesta" on Election Day.

Not that long ago, the U.S. Senate race in Indiana was one Republicans counted on as an easy victory this November. But the calculations have shifted rapidly in the past month, with Democrats now believing they have a real chance to switch the seat from red to blue.

Senator Richard Lugar says he will not campaign for the man who vanquished him in May's Republican primary.  Lugar told conservative Indiana blogger Abdul Hakim-Shabazz in an interview posted Monday that he would not actively support Republican Senate nominee Richard Mourdock on the campaign trail. 

Senate Republicans are jumping into Indiana's Senate race with a new ad, outdoing a recent buy from national Democrats as the parties battle for control of the Senate.
