The overall record for Congress resides in the House, where the late Rep. Jamie Whitten of Mississippi served for 53 years, two months and 13 days. Thurmond would have to serve another full term after this and live to 106 to beat that. At 94 he's already the oldest senator ever. Thurmond credits his longevity to good genes, good diet, and daily exercise. Twenty minutes riding a stationary bicycle.
Political longevity takes a different regimen.
That's why South Carolina has elected him eight times since 1954. That's why there's a Strom Thurmond Highway and a Strom Thurmond Dam. These days many senators may stay a term or two. Many leave in frustration. Thurmond chairs the Senate Armed Services Committee, champions defense and calls it all a challenge.
