Louis Napoleon Bonaparte, nephew and step grandson of Napoleon I, Emperor of the French, served as the first President of France, and was the only president elected in the second republic, because he would goon to abolish it in favor of a second empire. Suppose though that either the 1849 constitution itself, or the subsequently enacted lection law(s) forbade family members of former monarchs from seeking the presidency? Who wins the election, OTL's runner up? Someone else? Does the Republic survive? What does that mean for Italy, Prussia/Germany, Mexico, and everyone else? Discuss.
