You don't have to run faster than the zombies -- you just have to run faster than a Democrat.

A new YouGov poll of 1,000 Americans finds that, by a wide margin, Republicans are far more confident than Democrats in their ability to survive the apocalypse. Forty-three percent of Republicans say that, if the apocalypse were to strike tomorrow, they would be sure to outlast most other people in their community. Only 22 percent of Democrats say the same.

Republicans and Democrats also have very different conceptions of what the apocalypse would be: 27 percent of Democrats say that climate change would be the most likely cause of a coming apocalypse, compared to just 5 percent of Republicans. Republicans were more likely to cite nuclear war (36 percent), biblical Judgment Day (13 percent) and worldwide revolution (11 percent) than were Democrats. The parties are in agreement, however, on the odds of an apocalypse caused by zombies or aliens -- between 1 and 2 percent.

One reason Republicans are more confident about their post-apocalyptic survival odds is that they spend more time thinking about these things. Twenty-two percent say they have thought about preparing for a natural disaster "a great deal," and 35 percent have a natural disaster plan that all members of their family know about. By contrast only 14 percent of Democrats have devoted a great deal of thought to natural disaster planning, and just 18 percent have a disaster plan.
