The danger is that what some folks have been hoping will happen is still a possibility - ie: positioning Kasich as 'the moderate choice'. He's trying to take advantage of the media narrative of Trump being out on one extreme and Bernie being out there on the other extreme, with Kasich in the middle. And never mind Hillary or Ted because they're both kookie too, just in a different way. What ya really need is a kindly conservative like Plain Ol' Gee-Golly John.
Kasich's record is pretty easy to characterize as Authoritarian and Austerian, along with Privatizing and (at least Semi-) Theocratic. And, with that video, we could add Tone Deaf or maybe even Brain Dead. It's pretty easy to find lotsa criticism for that record online.
A lot of weird shit could happen in Cleveland - Kasich's back yard btw. Right now, there's a GOP rule (I think it's #40b) that's being interpreted as saying you don't get nominated if you haven't won a majority of delegates in at least 8 primaries. Lotsa speculation and wrangling over that one. Parties almost always open their national conventions with a few sessions of their Rules Committees, so we'll just hafta wait to see what silliness pops up this time around.
I think Kasich's pretty sure he's out, but that doesn't mean he can't be King-Maker; and it doesn't mean he won't make a play for Party Savior etc etc etc. So Kasich's job right now is to put himself somewhere between Trump and Cruz, and to re-paper the GOP with a plausible veneer that lets 'em Etch-A-Sketch their way back to the 90s when they were a big steamin' pile of freakzoid zealots, but they were all a lot better at pretending they weren't.
Here's the thing: Don't be fooled by all this Moderate-By-Comparison bullshit that the PR guys are peddling - a smiling hyena will still eat your kids.
This shit prob'ly gets worse before it gets better.
