Correction:

Hipólito Mejía's regime DID planned to stay in power even in the face of electoral defeat.

Wikipedia is based on QUOTED INFORMATION, and based on that, here's a quote from a reputed professional newspaper, citing the then Dominican Secretary of the Armed Forces:

"hubo riesgo de un estallido social...debido a que grupos armados pretendían desconocer los resultados de las elecciones"

"there was a risk of a social outbreak... in lieu of armed [forces] groups that pretended to ignore the electoral ballot's outcome"
