If Lugar should pull this out, then an investigation needs to be done of Cantor. I knew he couldn't be trusted, and now we have a reason why.
This is why term limits are needed and every single politician in Washington DC needs to be retired, right now!
Investigate and drive from public life in well-deserved disgrace: Boehner, Cantor, McCarthy as well as Lugar regardless of whether Lugar wins the primary or not.
