The Bernie article about socialism is a 'meh', article. It has no bearing on his reputation. Bernie has raised the 2nd most money of either party candidate with NO CORPORATE donations. The media does not tell that story. That is HUGE obviously. Trump, and most of the Dems except Warren have accepted a huge amounts of PAC money and big money donors, etc.
The well over 100 million dollars Bernie has raised with small donations is unprecedented and is being under reported because Faux..er..ah..I mean Fox News, CNN, MSNBC, are all part of big corporations that buy off both parties.
That is why they are scared as hell about Bernie because he is proving (along with AOC and the squad) that not only can you win without taking bribes you can raise just as much money doing it.
Republicans don't have that ability. The first Republican candidate who can manage that will be able to use that as a platform to rise.
So, trying to paint Bernie as fake or whatever, even if its true, is a non starter. It's falling on deaf ears. He came out of the Warren, sexist thing recently getting even more support. Warren lost that PR battle. Trump got impeached going after the wrong candidate, like the dunce he is. Bernie, not Biden was the real threat. He will lose against Bernie, and lose fairly big. This will depend in part on Bernie's running mate. If I had to suggest a person for Bernie, I'd say Julian Castro, or a moderate woman but not Warren.
