Just as with the case when matched against Hillary Clinton, Barack Obama would perform better with more highly-educated voters than John McCain, according to a Gallup analysis of its polling conducted March 31 – April 6. However, the gap between the two is much less marked than it is between Obama and Clinton. McCain leads Obama among voters with a high school education or less by 46 percent to 40 percent, with a 3 percent margin of error. They are essentially tied among voters with some college or a college degree, while Obama leads 52 percent to 42 percent among those with postgraduate education. Clinton would lead McCain 48 percent to 43 percent among voters with a high school education or less but runs behind McCain in all the groups with higher education levels.
