I can't help it - they just collapsed morally, so you can't help but feel disgust. As noted, there are historical Republicans I greatly admire. As recent as the early 90s, when I KNEW the Republicans were wrong, they did not induce disgust. Clinton induced disgust. Somewhere in the Clinton years the entire Republican effort just seemed to degenerate in a fiendish, counter-revolutionary rage against the social change of the 60s.
It's almost like a shameful thing for them to admit that people need real help, not "opportunity". The help they need is to be allowed to feel worthwhile by working and contributing - it's not much, but it's beyond the Republicans to understand what this means.
