Obviously time will tell, but it doesn't look like "Podemos" will fade away anytime soon.

Spanish politics have been very polarized with only two major parties sharing the power since the end of Franco's dictatorship (late 70s). During the last few years (and amplified by the economic crisis) people have been growing weary of their actions and general perception of impunity. Podemos is a young political party born as a reaction to that.

Here [1], you can see the last official government polls (from July 14), where the declining trend for major political parties is very clear, and Podemos as a new party is the 3rd most popular option. The next polls should confirm the trend, but the general feeling in Spain is that Podemos is still growing in popularity.

Note: I'm originally from Spain, although not currently living there.

edit: This additional poll from Sept 29th [2] (in Spanish) confirms the Podemos rising trend I was referring to.
