His opponent, David Perdue, has led major national corporations and has run an amazingly strong race for a newcomer to statewide elected politics.
Most of the polls indicate that Kingston leads the race, although Georgia's odd open primary rules, and its electorate's increasingly notorious lack of appetite for actually voting, makes the race a hard one to call.
Still, the themes of the race, and indeed the players backing the various candidates, debunk the concept that Republican voters will be so obsessed over "tea or no tea" as to somehow boycott nominees who like their politics hot and with sugar, or prefer something else in their cup. Kingston has managed to collect the support of many leaders of the various tea party organizations in the state. This is despite the fact that he has strong backing from "the U.S. Chamber crowd," often viewed as enemies of the tea party movement in other GOP contests this year.
Perdue, ironically, is viewed to be the candidate supported by many of the so-called "silk stocking" Republicans who admire his rise to national CEO stardom and his willingness to seek office. He has his endorsements as well, including one from businessman turned presidential candidate Herman Cain.
But in this race for every Herman Cain who supports Perdue, there is a Newt Gingrich who has endorsed Kingston. Whether the winner is frontrunner Kingston or dark-horse Perdue, both will likely enjoy a unified GOP electorate as they face a strong Democratic nominee, Michelle Nunn, in November.
That must be the case for Republicans and conservatives in every state with a contested battle for the U.S Senate this year. Without a united effort and strong voter turnout, the Senate could remain in the hands of the Democrats.
