Beyond that we are ever so vulnerable to cyberattacks and hacking. See the quote below,
In assessing Donald Trump’s presidential victory, Americans continue to look away from this election’s most alarming story: the successful effort by a hostile foreign power to manipulate public opinion before the vote.
U.S. intelligence agencies have affirmed that the Russian government directed the illegal hacking of private email accounts of the Democratic National Committee and prominent individuals. The emails were then released by WikiLeaks, which has benefited financially from a Russian state propaganda arm, used Russian operatives for security and made clear an intent to harm the candidacy of Hillary Clinton.
Plenty of Americans obviously bought into the propaganda, even those on the left where people were quick to believe and hold onto the claim that the election was rigged against Bernie Sanders.
News stories on the DNC emails released in July served to disrupt the Democratic National Convention, instigate political infighting and suggest for some supporters of Sen. Bernie Sanders (I-Vt.) — without any real proof — that the Democratic primary had been “rigged” against their candidate.
Russian (and former communist) propaganda has traditionally worked exactly this way: The more you “report” something negatively, the more the negative is true. Trump and supportive media outlets adopted the technique and reveled in information gained from the illegal Russian hacking (as well as many “fake news” stories that evidence suggests were generated by Russian intelligence operations) to make exaggerated claims (“Hillary wants to open borders to 600 million people!”) or to accuse Clinton of illegality, corruption and, ironically, treasonous behavior.
The email operation increased negative stories about Clinton, fueled an immense propaganda attack and diminished coverage of actual issues. The large polling lead Clinton gained after the debates slipped significantly under this barrage of negativity
