More than half of Republicans and Republican-leaning independents, 58%, do not express a preference when asked in an open-ended format -- with no candidates' names read -- whom they are most likely to support for the party's 2012 presidential nomination. Those who do have a preference most often mention Mitt Romney and Michele Bachmann.
Open-ended questions usually produce a higher percentage of "no opinion" responses than do questions in which respondents are offered choices, so it is not unexpected that the percentage with no opinion is much higher than in the closed-ended format.
Results for this Gallup poll are based on telephone interviews conducted July 7-10, 2011, with a random sample of 482 Republicans and Republican-leaning independents, aged 18 and older, living in all 50 U.S. states and the District of Columbia. For results based on the total sample of Republicans, one can say with 95% confidence that the maximum margin of sampling error is ±6 percentage points.
