Socialism has other elements
I think your argument might be more convincing if you actually mentioned these elements.
Marx did not think it was socialism
Other people had other definitions even before Marx, so I'm not sure why his should be the only valid definition.
Just my two cents.
there are other elections besides the federal ones

Politicians should always care about the political opinions of the population and not only 6 months before elections
