| Embryonic stem cell research |
McCain would support legislation that would expand federal funding for embryonic stem cell research and place fewer restrictions on it. But in a nod to the anti-abortion community, his adviser also has said that he hopes to not have to rely on embryonic stem cells in the future. |
| Scientific Research Funding | McCain is sympathetic for the need to fund basic research, but is not sure where the government would find that money. |
| Energy Policy | McCain is a proponent of nuclear energy and believes that tax credits and other incentives will reduce America’s dependence on oil and gas. |
| Science Education |
Although having a number of educators providing advice on education policy, such as Eileen Weiser of the National Assessment Governing Board and Phil Handy, former chairman of the Florida State Board of Education, McCain has yet to officially release an education policy. |
| Evolution vs. Religion |
"I believe in evolution," Sen. John McCain said. "But I also believe, when I hike the Grand Canyon and see it at sunset, that the hand of God is there also." |
