Sometimes there's a problem when a far-left reporter admiringly covers a far-left political official or candidate. What occasionally happens is that items which would clearly be objectionable to sensible people make it to print or onto the airwaves because the lefty journalist doesn't recognize how problematic they are. If he or she did, it would be kept out of their reports.
At NBC News, former Salon.com columnist Alex Seitz-Wald's far-leftism is beyond dispute. Writing that conservative outlets ignored the Kermit Gosnell trial as much as liberal outlets did, claiming that cable news king Fox News is "a stable for journalists who have fallen on hard times," and gushing over the appearance of Hillary Clinton's "Scooby van" in Iowa clinch that evaluation. On Saturday, Seitz-Wald allowed a quote from Bernie Sanders' statement on Donald Trump's cancellation of his Chicago speech on Friday into his report on how the cancellation came about. Big mistake.
