So, if Bernie "Honeymooned in Moscow" Sanders wins the presidency (humongous "if"), I don't think we have to worry about Socialism.
He's been in Congress as a Rep and Senator now for 29 years (Rep: 1991-2007; Sen: 2007-Present). I went to Congress.gov and did a search of his record.
He's sponsored 934 bills over his 29 years. Of those only 3 have been signed into law, and 2 of those were to rename a Post Office.

To be fair, he's co-sponsored a higher number, and 221 of those became law (218 if you don't count the 3 he sponsored as the primary).
Many of the laws co-sponsored were to authorize Congressional Gold Medals for people and organizations -- about 23.
A bigger number were resolutions, like condemning the violence at Charlottesville, Va. He also signs onto the bills to provide annual COLA increases for Veterans, as if that's not going to be close to automatically signed by the President. Another co-sponsored law was to let the Post Office raise funds for breast cancer awareness.
Somehow, I'd think in his decades of gov't service, he would have a better resume.
It lends credence to Hildabeast's recent comment, that nobody in Congress likes Bernie, and nobody wants to work with him. If that's true (considering the source), I don't think Bernie has the backing to implement his Socialist ideology.
