How could a French Second Republic survive?

I'm currently looking into, and beginning the first draft of an alternate long nineteenth century for France. One of the ideas that I have been playing around with is the possibility of having a stable Second Republic without the ascencion of Louis-Napoleon as President?
It's my understanding that the reason the second Republic was a failure was due to there being no resolution concerning disputes between Dupont and the Assembly.

In what way could the French Second Republic have survived?
 
It's hard to say. I'm inclined to think that the Second Republic, for which I have a soft spot, couln't have survived for long for structural reasons.

Mutatis Mutandis, and excepting, of course, the trauma of military defeat, there are a number of similarities between the Second Republic and the Weimar Republic, especailly when it comes to weaknesses. Louis-Philippe, ableit very impopular, has been ousted from power by a urban, proto-socialist revolution. Whereas many peasants welcomed the revolution, a rift appeared between Socialists and Liberals and the more conservative majority of the population, escpecially in rural areas where the nobility and landlords had much power. Note that many Royalists, who hated Louis-Philippe, thought that the universal suffrage would bring them back to power.

The Liberals, who dominated the Republic in the first months, crushed Socialist demonstrations in Paris and Lyon, and sided themselves with the Conservatives and Monarchists. Incidentally, they favoured the electoral victory of the Monarchists in 1848, who supported Louis-Napoleon, very popular because of his Napoleonic aura and his socially advanced speeches, for the -then direct- presidential election, thinking that he would bring back a king. Thiers, who acted at the time as Von Papen would some 80 yeras later, explained to his political friends that Louis-Napoleon was "an idiot we will drive the way we want". He had the same success as Von Papen with...Well, you know...
 
First, I think the question is which 2nd Republic are we referring to here, the provisional government, or the constitution ratified in November of 1848?

I agree that the Second Republic had structural problems, but those problems merely made it unrepresentative of the whole of France. What really killed it was the fact that no constituency really had a stake in the 2nd Republic. The Parisian mobs despised it for the June Days, the nobility viewed it as illegitimate, and much of the rest of France was apathetic, or in any case not willing to fight for it.

I think the Constitution left the door open for a strong president, who had the latent power to make himself a strongman, if not an emperor like Napoleon III. You need a George Washington type to win the first election to build the Republic a base of support. Of all the candidates for President, I think Lamartine would fit the bill the best. Cavaignac might have made a capable president, but he also could have ended up a dictator like Napoleon, but one less likely to formally dissolve the Republic.
 
If Cavaigniac wins the Presidency, the Second Republic will get along just fine, at least until a major war with Prussia/Germany (and it's not impossible for it to survive that). The royalists are a controllable problem.
 
Louis Napoleon landed in France, proclaimed himself emperor, got jailed, and then escaped.

Have him get shot at any point in the festivities, stay in jail, or head back to England with his tail between his legs when he escapes and decide not to come back and you don't have OTL's Napoleon II.
