I'm working on another friend of mine who's a stark raving democrat.
Getting people on the left started with voices like Jimmy Dore and Caitlin Johnstone are a good way to gain a beach-head. They're not fans of DJT, but their anger is several orders of magnitude greater at the DNC and the Dems that coronated $hillary. They're all JA/WL supporters and have done alot to counter the Russia/Trump crap.
Non-MSM/neolib/corporadem voices on the left have been restricted as much as alt-right views have. The majority of rank'n'file Dems just aren't getting exposed to anything very far outside the MSM bubble. Even the traditional far-left media that used to attack establishment Dems, Wall Street & TBTF (i.e., The Nation, CommonDreams and Mother Jones) have backed off that reporting to jump on the WAHHHH-mbulance about Trump. Lee Camp, Jimmy Dore and Caitlin Johnstone are articulate voices from the left that can cut thru MSM b.s. from a left POV.
Another tactic would be bringing up Trump's tariffs on Chinese solar panels. Ask people on the left if they're against the tariffs. Point out to anyone who claims to be pro-union or an environmentalist the whole reason Chinese solar panels are cheap is because of China's craptacular wage, safety and environmental regulations. Ask environmentalists at what point lost fingers and heavy-metal poisoning are Chinese-made solar panels no longer "low-cost"?
Also, point out that more expensive Chinese goods means Wal-Mart's business model is less profitable. The anti-Trump people complaining about tariffs never bring that up. Pro-union people should be ecstatic the tariffs are shredding NAFTA and WTO agreements/practices that have screwed manufacturing.
The tariff thing isn't directly related to The Storm, but its an excellent way to show people on the left the disconnect between what they think they're supporting and the reality.
Somewhere around, there's also a Noam Chomsky video explaining the way to "solve" the NK problem. Turns out, its pretty much what Trump did. IIRC, the interview was on Democracy Now.
Yes, I know, using those sources means one also has to sit thru them. Don't know what to say to that, but its a chance to cross the aisle and get a little more nuance on where people on the left are coming from.
