The reason the “news” channels asked those Republicans to appear on election night was because they already knew they were anti-Trump. The “news” programs could double down on their Trump hatred, while pretending to be balanced.
By the way, if you want to see really, really biased election night coverage, make sure you watch the British ITV and the Canadian CBC coverage.
Thank you for the ITV site; hadn’t thought of it. I did watch part of the CBC coverage on YouTube. Four very angry people, but the angriest was the one from across the border, GW Bush speechwriter David Frum who literally spat out his anger (Frum was one of the leading advocates for the Iraq War). People like Frum destroy any lingering conception that there was anything good about the Bush presidency. I like how they attribute Trump’s surprising win on many of these news outlets Eelction Night to “we found out there were a lot more racists in the US”, or “the uneducated people showed up at the polls”, or “the Trump voters are very angry”. Strange, you never heard a word about Hillary saying half the US consisted of “deplorables” or how she wanted to shut down the coal mines and coal miners, or how a very substantial part of her vote comes from the inner cities, where the schools are far worse than in rural or industrial America and where many of whose residents also aren’t known for their knowledge of physics or Shakespeare.
