While Mitt Romney and Newt Gingrich stand out as favorites among influential conservatives in early-voting states, the majority of local party insiders have not offered a public endorsement of any candidate, according to the latest Power Outsiders survey conducted by The Huffington Post and Patch.

More than one-third (37 percent) either are undecided, are unsure how certain they are, or could still change their minds about which candidate they plan to support.

The uncertainty is even greater in the Palmetto State, where 48 percent are undecided, unsure or admit they may still change their minds. Even though the primary is just 37 days away.

In South Carolina, less than 30 percent of our Power Outsiders have publicly endorsed a candidate. Nearly half of the 17 who have are behind Gingrich (eight), with Gov. Rick Perry (three), former Gov. Jon Huntsman (three) and former Gov. Mitt Romney (two).

Among those who have not endorsed a candidate, Gingrich leads the way among conservatives when asked who they would like to see earn the nomination. Twenty-two percent say the former House Speaker, while 10 percent say Romney and another 10 percent say former Sen. Rick Santorum.

When the endorsements and leanings are combined, Gingrich takes 36 percent of the support among South Carolina's conservatives, with Romney (14 percent), Huntsman (10 percent) and Santorum (10 percent) trailing. No other candidate is in double-digits, though Perry and Rep. Michele Bachmann are each at 7 percent.
