Also need to point out that in his first election Corbyn was only 7 seats away from winning, or 2,227 votes away from winning that election. So the conservatives and the liberal media and right wingers in his own party absolutely shat themselves and started doing whatever they could to make sure he didnt win the next one. Combined with the 2019 election being mostly about brexit and Corbyn being in an impossible position of trying to unite a party that was deeply split on the issue. meant he had his "historic" loss. And even then he still got 10,000,000 votes compared to Johnsons 14,000,000 so it really wasnt even as big of a blowout as the media pushed it as.
