Creation of the legitimate government and self-government institutions by means of democratic elections is a significant element of national and pan-European security, whereas it establishes internal and foreign policy stability guarantees. Power legitima- tion crisis incidents and foreign-policy deligitimization of some regimes in post-Soviet space requires precise problem review. The 5th of September 2010 referendum results in the republic of Moldova attest about the constitutional, political and legitimation crises. Besides the creation and extension of democratic institutions activities, non- government organizations and independent mass media, adoption of the legislation ac- cording to the world and all-European standards favors the eurointegrational pursuits of the Moldova republic, defined by its strategic priorities. Nevertheless, questions on foreign-policy power legitimization during elections are insufficiently known, particu- larly in the security context (in accordance with the citizens’ interests, society, govern- ment and European community). Electoral legitimation is implicated by the author as a process of electoral legiti- macy, supplied by power as a result of realization of direct democracy principles dur- ing the elections and referendums by electorate; consequently the political confidence is being transformed into power support. In the context of legitimacy types defined by M.Weber, D.Bithem and D.Held the author assigns these indicators of foreign-policy electoral power legitimation: degree of international community public trust to the legislative base of elections and civil so- ciety institutions (parties, NGOs, mass media) connected with elections (estimated by monitoring of qualitative changes of normative basis of the Parliamentary Assembly of the European Council, European Commission for democracy through law (The Venice Commission) and Bureau of democratic institutions and human rights of OBSCE in Europe in accordance with the main international-legal and political documents); trust degree in electoral process (observation of foreign states and international organiza- tions using OBSCE observation criteria; support degree of elections, referendums by means of public approval of the organizational activities of electoral process subjects, giving material and technical aid (financing of electoral bodies members’ training, providing of electoral bodies’ equipment, making of the voters’ electronic register) by the representatives of foreign states and international organizations.
