re: True conservatives never compromise
Can't say as I understand his expectations either, but 1) he's not unique in that rigid literalism toward campaign promises; and 2) I've seen it countless times over the years, particularly in the disillusionment toward Bush I, less so in the case of Reagan.
My father may exemplify that particularly dogmatic kind of voter who expects 100% of a politician's promises to come true. For example, he was rather upset that Bush didn't get all of his tax cuts--he "allowed" the Democrats to "get away with" reducing the size of the cuts. Any opposition victory, however slight, is a huge failure for his side, laid at the doorstep of the President.
