I have no idea how Hillary spoke of Stein; it is her supporters who blamed Stein (the same thing played out in 2000 with Nader).
Trump supporters could - and would - claim something similar if he had lost, but he won anyway.
When Hillary accused Tulsi Gabbard of being a possible Russian asset, she mentioned that Stein was a Russian asset.
BS on a moral equivalency between Trump and Hillary supporters. When the Dems lose, they come up with conspiracy theories. When Hillary lost, there were requests for recounts in WI, MI, and PA. There was a concerted campaign to persuade Trump electors not to cast their ballots for Trump in the Electoral College. Many Dems in Congress boycotted the Inauguration while Dem mobs protested it. Talk of impeachment began before the Inauguration. Over the past three years, four separate votes were taken in the House to impeach Trump.
We can recall the Dems refusal to accept Bush 43 as legitimate and the court battles over hanging chads. Stacey Abrahams still claims she won and blames voter suppression. The Dems are undermining our Republic by refusing to accept the results of elections. It is highly dangerous and irresponsible. Hillary and the Dems are still blaming Russian meddling for Trumps victory despite the findings of the Mueller report.
