At any rate, this is a pretty resounding mandate for the ruling coalition, which has been in control since the early '90s. A quickly growing economy--especially since leaving the union with Serbia--may have much to do with that. The pro-Serb opposition candidate appears to have received just over 20 percent, and a liberal candidate around 17 percent. The president is a typical European ceremonial president, so the significance of this is essentially as a voter endorsement for Đukanović's resumption of power and the ruling DPS (whose continued stranglehold over Montenegrin government is, however, a little worrying).
One interesting/misleading quote from the AP article is:
"Ethnic Serbs, who make up about 30 percent of the population, opposed the split."Note that the difference between "ethnic Serbs" and "ethnic Montenegrins" is political; they speak the same language (be it "Serbian" or "Montenegrin") and are the same in everything except for their ethnic self-definition. Compare to the "Moldovan" and "Romanian" languages, or perhaps "Valencian" and "Catalan." Therefore, the definition is somewhat tautological; "ethnic Serbs" by definition consider Montenegro and Serbia one country.
