Keith - how many more shovels and pick-axes are you going to wear out digging this deep hole for yourself...

There is actually a more dignified way for you to end this silliness.

You can just honestly admit you backed the wrong man and party,
and that you are yourself heavily disappointed to be so badly let down
for giving your dogged blinkered support to such cynical and ruthless self preserving liars...

You can take a more honourable path of backing down and eating humble pie...

That's what I'd do... and if you did that, I for one would have more respect for you.
