Could South Carolina be Mitt Romney's first stumbling block? A new Insider Advantage poll has Romney falling to 23% in the state, an insignificant two points ahead of Newt Gingrich's 21%. Rick Santorum is well behind them with 14%, followed by Ron Paul with 13%, Jon Huntsman with 7%, and Rick Perry with 5%. (The poll did not include Stephen Colbert.)
The poll is Romney's worst showing since the start of the new year, with the past three polls having him at 37%, 27%, and 30%, according to the Hill. The poll, writes Justin Sink, also indicates that Santorum's post-Iowa boomlet is dying down following his less-than-impressive New Hampshire showing. Perry, too, seems to be missing the boost he had hoped for, in the early state presumably best demographically disposed to him.
