The Democrats would rather not mention Russiagate and their impeachment effort because they were both spectacular failures. You can be sure, though, that we’ll hear plenty about them from the Trump camp. From Caitlin Johnstone at medium.com:
The only interesting thing about either of the conventions held by America’s two mainstream political parties this month was not anything that was said by the interminable parade of vapid speakers, but rather what those speakers did not say.
Despite their dominating mainstream news cycles for years on end, at no time during the four-day Democratic National Convention was the word “impeachment” ever uttered, nor was any mention made of the Mueller investigation into allegations of collusion between Trump and the Russian government.
Eight months after Democrats mounted a historic effort to remove Donald Trump from office, not a single speaker uttered the word “impeachment” during their four-day convention.
For Democrats to completely omit impeachment from their convention was once unthinkable. Democrats had mounted a case that Trump had abused his power to blackmail Ukraine into investigating his political adversaries, including Biden. And they made an existential argument that without removing him from office, Trump’s behavior would get worse and democracy itself would be at risk.
Special counsel Robert Mueller’s investigation of the Trump campaign’s ties to Russia — which Democrats once thought could topple Trump for obstruction of justice — also went unmentioned, even as it was a defining feature of Trump’s nearly four years in office.
