Richard Lugar and Richard Mourdock look to be neck and neck coming down the final stretch in the race for the Republican nomination for Indiana's U.S. Senate seat.
The stakes are high for Lugar. At stake is his political legacy. Will he be able to go out of the Senate on his own terms, or will he be retired before he's ready? Mourdock hopes so, and he's running extremely hard to make it happen. It's a referendum on Lugar, as political expert Brian Howey has said, and the longtime Senator is hoping to weather this political thunderstorm.
Everything, however, will come out to turnout on Primary Tuesday. If the party establishment shows its face and its votes at the polls, that could offset the Tea Party uprising that's backing Mourdock. If that old guard stays home, Mourdock will be around in November.
