This poll also tested the positive or negative effect of various possible vice presidential candidates. Only in the case of Mitt Romney did more people say the choice would make them more likely rather than less likely to support McCain, and that was within sampling error – 20 percent more, 16 percent less. Ridge showed a net negative impact of 6 points, Connecticut Sen. Joe Lieberman of -7, but the overall impact of all was small – given current knowledge of their positions on the hot-button issue of abortion.
