According to the just-released poll, 28 percent of Clinton's supporters would back McCain should the New York senator lose her quest for the Democratic nomination.
That compares to the 19 percent of Obama supporters who say they will favor McCain should Clinton be the party’s nominee.
"[The results] suggest that some Clinton supporters are so strongly opposed to Obama (or so loyal to Clinton) that they would go so far as to vote the "other" party's candidate next November if Obama is the Democratic nominee," Frank Newport of Gallup said of the survey's findings.
Newport also noted that the poll's results are likely the result of the heated battle for the nomination, and the number of the party’s defectors to McCain is likely to decrease after Democrats choose a nominee and the focus shifts to defeating the Arizona senator.
The poll was conducted March 7-22 and carries a margin of error of plus or minus 2 percentage points.
