In the latest survey conducted by Public Policy Polling, 507 likely voters were polled on their general thoughts about the various impacts that a running mate has on a presidential election, and also the overall impact a vice-president has on the policies of the president.
46% of the respondents said that the presidential candidate's choice of a running mate has a strong impact on their vote. I'm skeptical about the validity of these responses because that would seemingly imply that almost half of the voting population in North Carolina would potentially change their vote solely based on the candidate's running mate. It also doesn't fully match up with the other survey responses, because when asked about Clinton's affect on an Obama vote, 32% said they would vote for Obama no matter what and 33% said they would vote for McCain no matter what. This shows that only 31% are actually more or less likely to vote for Obama based on his choice of running mate.
