Is that saying meant to cover baseless assertions about someone's actions? Hillary Clinton was involved in enough shady shit to not need to make stuff up. If someone says that she donated to her opposition's campaign they should have evidence to back that up. Otherwise they just give ammunition to people convincing others to ignore real, substantive criticisms against Trump.

That article mostly describes her campaign focussing on criticizing stronger and more likely candidates early on when the Republican nomination was still up for grabs. That just makes tactical sense. Otherwise you might as well also accuse her of being involved in a conspiracy to get Vermin Supreme in power too.

You can say the fact that Hillary is a woman contributed to her loss. You can even argue that it was enough to make the difference in Trump winning. But the main reason she lost is because she was still otherwise a weak candidate overall.
