I don't know what "the Republic of Maine" is, but the Constitution of the State of Maine is here, and it says nothing like either of those things.
The Republic of Maine is the name for the free country that the state of Maine becomes immediately after the secession vote on June 12, 2018. What you were reading is the beginning, it will be done within the next two years, of the Constitution that will go into effect immediately upon the success of the secession vote.
While no more than what is currently up is official, more will be put up this coming Saturday, I can answer, within a day, almost any question you have concerning the new Constitution, not the exact wording, but the essence of what it will be.
As and example, all land use is limited to the local level, Maine will be at perpetual war with the UN, therefore allowing no entry into the UN or any support for it's military or social agendas.
