Donald Trump is a menace, and his arrogance, ignorance, and petulance, put the country we love in immediate peril upon his ascension into the presidency.
It is also clear that this election was not fully legitimate, with direct influence from the Russian government, all the way up to Vladimir Putin, skewing the results of the election.
Thus, if Trump is able to assume office with the legitimacy of his victory being unclear at best, then Obama -- a man who clearly won two elections and has demonstrated competence in the position -- should be able to stay in office. In fact, he has a duty to stay in office for the sake of preserving, protecting, and defending our constitution, something Trump clearly will not do.
Thus, Obama should employ military force if needed and stay in office.
