IBOPE Zogby International conducted an online survey of 1,581 voters. A sampling of IBOPE Zogby International's online panel, which is representative of the adult population of the U.S., was invited to participate. Slight weights were added to region, party, age, race, religion, gender and education to more accurately reflect the population. The margin of error is +/- 2.5 percentage points. Margins of error are higher in sub-groups. The MOE calculation is for sampling error only.
IBOPE Zogby International also conducted an online survey of 796 likely Republican primary voters. The margin of error is +/- 3.5 percentage points.
