Hillary might have had a lot of advertisement money to play with but we also know that outside influences were promoting Bernie on social media to create a spoiler effect.
What spoiler effect? He was running for the Democratic nomination, not as a third party candidate. And with a very small number of vocal exceptions, everyone who voted for Bernie in the primaries voted for Hillary in the general. It was her absolute failure to get independents in multiple flyover states that lost her the election. And a huge part of that is her attempt to appeal to republicans. A strategy that also failed spectacularly for Harris in 2024.
This is why the DNC will fight to keep him exactly where he is. Just watch. In 3 years they will be funding his campaign against anyone who dares to challenge him in the primary.
