I want to know the answer to the following question:
Who was the first person elected under the new constitution?
All the background I'm provided with is that "Although unable to resist the popular demand for the expulsion of the Spaniards, he soon quarreled with the legislature, which declared itself firmly for Guerrero, and announcing his support of Bustamante's revolution, he suspended, in March 1830, eight members of that body, the vice-governor, and several other officials, and expelled them from the state.". Is that enough to answer the question?
Answer: no
