S.C. Sen. Tom Davis – the leading fiscal conservative in South Carolina state government and one of the most coveted endorsements of the 2012 “First in the South” presidential primary – will announce his support for U.S. Rep. Ron Paul on Sunday.

Davis will endorse Paul’s candidacy at a campaign event Sunday evening in Myrtle Beach, S.C. – confirming a report published earlier this week on Buzzfeed.

Paul’s campaign has described Davis’ forthcoming endorsement as “consequential” and “game-changing.” Why? Click here.

A first-term State Senator, Davis wields a disproportionate impact given his stellar fiscal voting record and his advocacy on behalf of key state-level reforms including a taxpayer rebate fund and an aggressive government restructuring bill (unlike the “restructuring in name only” pushed last year by Gov. Nikki Haley).

Davis has also pushed for individual income tax relief as opposed to taxpayer-funded incentives on the job creation front – arguing that the latter only shift the state’s tax burden onto small businesses.

Most importantly for the state’s economic future, however, Davis has been the leading proponent of a public-private Jasper Port terminal – although S.C. Gov. Nikki Haley’s recent “Savannah River Sellout” may have doomed that project.

“Senator Tom Davis’ fiscal conservative credentials are outstanding,” Matt Moore, executive director of the SCGOP, said recently. “Any candidate would do well to gain his endorsement.”

Not surprisingly, Davis’ nod has been among the most sought-after of the primary season. Last year, The Politico named him  one of its “50 politicos to watch,” while a recent CNN story referenced him as a “rising star.”

In addition to Davis, several other leading fiscal conservatives in the S.C. General Assembly are also rumored to be endorsing Paul in the coming days. So stay tuned …
