again this is not an actual TV commercial, just a web video. I think the main target of this is the establishment elites. Kasich is trying to send the message that he is the one who is willing to take on Trump directly, and therefore they should get behind him. Not sure it will work but what does he have to lose at this point.
'You can lead a horse to water, but you can't make it drink' or 'no joy can come from causing grief'.
As a religious man Kasich should know it.
Offending bully Trump is a bad tactics.
Kasich has already lost though. It's just like when Jindal attacked Trump, nobody cared and Trump brushed it off. The only difference here is that Kasich's super PAC has millions of dollars for this so it'll be hard to ignore. Kasich isn't afraid of going from 3% to 1% at the hands of Trump though.
