INDIANAPOLIS (AP) — Indiana Sen. Richard Lugar's allies have largely disappeared from the television airwaves in the days before Tuesday's primary. It's a sign that even Lugar's friends think the six-term Republican is in trouble and could lose to tea party-backed challenger Richard Mourdock.
Mourdock's backers, meanwhile, have stepped up their criticism of the 80-year-old Lugar as too moderate for the GOP-leaning state and out of touch after 36 years in Washington.
Total ad spending intended to benefit Mourdock was pushing toward $2.3 million and could top that in the campaign's final week.
Lugar and his allies have spent $3.5 million on TV since the beginning of the year trying to persuade Republicans to stick with him.
