A former presidential candidate is going to bat for a candidate for Indiana Senate. Arizona Senator John McCain is headed to Indianapolis this week to campaign for fellow Republican Richard Mourdock. McCain is scheduled to appear at a Mourdock fundraiser breakfast Wednesday, then participate in a roundtable discussion with Indiana business-people about the economy. The visit is one of several reported appearances by high powered Republicans to the Hoosier State. New Jersey Governor Chris Christie is slated for an October 22, fundraiser in Indianapolis as well.
