hi tkc,
the word i use for obama is fastidious. never wants to dirty his fingernails. being a leader means you may get to choose the sort of dirt you dig in, but you have to do some digging in a dirt-covered world. obama almost looks offended by the need to do so.
bernie suffers from much the same problem. he speaks as if we can have the nice things and we should just ignore the unpleasant ones. this way he avoids discussing the difficult challenges he will face.
hillary is more pragmatic but follows rather than leads too much (witness her dependence on polling - who knows what she believes these days other than first woman president). maybe the bernie challenge will push her off the fence.
on the other hand, with the gop field, you get folks who appear to want to make difficult choices. unfortunately they look likely to choose the wrong ones in almost every scenario anyone asks them about.
oy vey. looking forwards, hc is the best of a bad bunch. the hope is that the us survives this ugly choice and 2020 brings a stronger slate.
