Red Nation, Blue Nation

Listening to the recent debates among the candidates, monitoring their Websites and reading the poll numbers, one gets the impression that the Republican and Democratic primary electorates are living in two different nations — or the same nation that faces two very different threats.

The Republicans want to protect us against Islamist terrorists. The Democrats want to protect us against climate change. Each side believes the other’s fears are largely imaginary. Rush Limbaugh regularly treats global warming theories as a "hoax." A prominent political scientist dismisses Republican candidates’ appeals as sounding "like the day after Sept. 11." When asked about possible new attacks, Democratic candidates — with the exception of Hillary Clinton — talk about seeking international support and understanding. Asked about climate change, Republican candidates — with the exception of John McCain — talk about getting more information.

 Both threats are, in different ways, known unknowns. We don’t know where the next Islamist attack will come — Fort Dix? JFK Airport? — or when. We don’t know the effects of warming temperatures, or at what rate they might become apparent. And we can’t be sure whether our efforts to parry either of these threats will be availing. We can try to track down loose nukes, shadow suspected terrorists, protect the very many vulnerable potential targets in our open society. But the terrorists only have to succeed once, and we must succeed every time.

Similarly, we don’t know to what extent a reduction in carbon emissions will reduce global warming. Some scientists tell us that there has been greater climate change in past history due to factors over which we have no control — such as solar cycles and shifting ocean currents. In the 1930s, British Prime Minister Stanley Baldwin predicted that "the bomber will always get through." We fear the terrorist will always get through, and we know the sun will.

 The difference between the two parties’ constituencies reflects two different views of America and the world. Those who see Islamist terrorists as the proximate threat see a world in which Americans are largely blameless. Rep. John Murtha may think that the recently foiled plot against JFK Airport was a response to American intervention in Iraq, but September 2001 came before March 2003.

What we are guilty of, in Republican voters’ view, is at worst a botched attempt to spread freedom and democracy in the world. And the people who would attack us are, in this view, truly evil. Negotiation, propitiation, appeasement, confessions of guilt — none of these will reduce the threat. Vigilance and going on offense will.

Those who see climate change as the proximate threat take another view, one that has evolved into a kind of secular religion. Debate on the science of climate change must be shut down — you must have faith.

We Americans have sinned, and we will be punished unless we repent and change our ways. We have been selfish, and we have failed to heed the advice of the more enlightened and sophisticated nations of the world. We must do penance by sacrificing some of our comforts (though not the gigantic houses and private jet travel of Al Gore or John Edwards). We must reduce carbon emissions by some tremendous percentage.
Left mostly unspoken is which of the two mechanisms to reduce emissions will be used: a carbon tax, which will impose significant costs on everyone and big costs on some (coal miners, steel manufacturers), or a cap-and-trade system, which can be gamed by sharp operators (it was central to the business model of Enron).

He who defines the issues tends to determine the outcome of the election. When pollster Peter Hart asked a bipartisan focus group which candidate could best protect the nation, several people mentioned Rudy Giuliani and John McCain, one mentioned Barack Obama, and no one mentioned Hillary Clinton. Evidently these people, unlike international elites, see the threat as Islamist terrorism and not climate change.

We know which seems more threatening to Republican and Democratic primary voters. But what about independents, who favored Republicans in 2002 and 2004 and Democrats in 2006? The answer may tell you which side wins in 2008.
