The GOP’s longest-serving Senator got the boot in the Indiana primary Tuesday, putting an end to his 36 years in office.

It is also shaking up the nation’s political scene.

U.S. Sen. Richard Lugar issued a lengthy public statement following the voting, but the world’s only senior citizen with a Twitter account (besides 90-year-old Betty White) might've officially abandoned him as a loyal follower.

Lugar's last tweet went out May 1 while he was in the final week of an intense poll battle with State Treasurer Richard Mourdock. Then, the account gurgled and sort of died.

Between a lackluster campaign against his Tea Party opponent (none of his Tweets were directed against Mourdock) and moving out of his home district, the senior congressmen finally lost the seat he had held since 1976. 

Mourdock, on the other hand, sent out a celebratory tweet: "Come join our team at the Indy West Conference Center for the Victory Party! Doors open at 7pm." Then, he followed up with an honorable salute, 12 hours later: "Senator Dick Lugar has served Indiana with distinction for 35 years of his life, and we are grateful."

So far, there's been no response from Lugar.

C’mon Dicky, almost 14,000 people wanna know your retirement plans!
