And you think that Democrats are not the same? When Bernie ran in competition with Hillary, Bernie was by far the stronger candidate. Poll after poll showed that he would win massively against Trump, but Hillary would barely scrape through. On the day that the DNC gave Hillary the nomination, I stated loud and clear, "Trump will win."
Why did they insist on Hillary rather than Bernie? Same reason that they turned down all the other candidates in 2020. They want a different economic system - the same one that Reagan outlawed. They want a mixed economy back, and they want to eradicate laisse-fare capitalism which has destroyed every country that switched from the mixed economy.
Why did so many Dems support Hillary? Because the Dems consist primarily of women, and many of them are feminists, and they wanted a woman president, regardless of the fact that she is dishonest, supported fracking, war, and is corrupt as hell. They blinded wanted her because, well, you, now, the Dems stand for equality. Ideology before benevolence and practicality.
