Did Facebook Hack the 2016 US Presidential Election?

In 2018, the house Democrats released a set of like 3,500 ads which were run by the Russia-based IRA during the 2016 US election presidential election. Did these ads actually influence people's ideologies and did it actually change people's ideologies? One of the interesting findings in that was not really. People who were left leaning, they would probably go even more left leaning or people who were right leaning,. I mean that also aligns with psychology and political science literature. It's very hard to change someone's ideology. That was one of the preliminary findings of our paper. Like who were these targeted to? Did it actually matter based on say between group and within group group as in ideological groups
