How did Louis Napoleon win public approval for his seizure of power?

In the second French empire in the years of 1852 to 1870, Napoleon III ran the French government much like a Dictatorship. Although ostensively a "democratic" style, the government was typified by a secret police force, press censorship & "controlled" elections, rather than free elections.

Napoleon III gained early support by:

A. Legaizing unions granting them a limited right to strike;

B. Providing the city unions work on city projects;

C. Improving banking & credit facilities;

D. Promoting railway & canal building;

E. Encouraging the growth of industry;

F. Expanding French colonial rule in Algeria, colonizing parts of Southeast Asia; and

G. Forming an alliance with England to defeat Russia in the Crimean War.
