A central question for centrists in any political year is, which candidate is most likely to unite the country?
In the New Hampshire primary, MSNBC exit polls report some useful results for this question. Voters were asked, "Regardless of how you voted today, which one of these candidates would be most likely to unite the country if elected president?" Among those who voted in the Democratic primary, 51% thought that Barack Obama would, while only 28% thought Hillary Clinton was a uniter.
Strangely, they did not ask this question of Republican voters.
