|You think people "who need the NHS" should logically vote for Corbyn, but they don't think they should.|
That's Corbyn's patented 'voter repellent, unkindness and dis-ingenuousness. Corbyn doesn't care about the unemployed, the elderly, the crippled or anyone in particular, he merely 'cares for their cause' - which is not at all the same thing at all.
When push comes to shove, your gut feeling and his past behaviour tells you cold-blooded Jeremy is just as likely to send the elderly to death camps as to the NHS. Even if his schemes result in untold suffering, they will still have been right "for the greater good" or some similar profound-sounding bullshit that tumbles out of his mouth at that moment.
When Hillary Clinton was running I knew she would lose when she answered this question: "Some Republicans are looking to roll-back Medicare. Do you support Medicare?"
Hillary's answer" "Yes, of course I support Medicare. I strongly support Medicare in its current form for at least 12 more years."
Hillary wasn't electable, not just because of that one answer, but because someone emotionally out of touch enough to say something that creepy is also routinely saying other creepy stuff I haven't heard yet.
This is a different answer to what Corbyn would give regarding the NHS, yet exectly the same. Corbyn's sincere looking assurances leave you with the same disquieting anxiety that he could just as easily close the NHS next year based on some political theory - like "it's their own fault for being ill".
The problem isn't Jeremy Corbyn's 'platform'. The problem is Jeremy Corbyn.
