Does Hillary Clinton display any skills at 'Presidenting' that set her apart from Biden, Cuomo, Warren, and company? How much of this can we determine from past achievements?If I had an answer for that question...
Here's, I guess, what I would say:
1. Experience is better than lack of experience. Broader experience is better than narrow: Clinton's particular strength is that she's been involved in state government, she's been, if not quite White House staff, pretty close to it; she's been in Congress (don't forget that she's been House committee staff as well as of course being a Senator); and she has executive branch experience, and pretty much top-of-the-line at that as Secretary of State.
2. Workhorse is better than showhorse; evidence that the candidate can master her brief is a plus, as is evidence of a good grasp of multiple issue areas, and evidence of coalition-building and working well with others within the political system.
3. Pragmatism is better than ideological crusading. Also, look for evidence in governing record, not rhetoric; Reagan was a more pragmatic governor, and president, than his rhetoric would have suggested.
4. You do want someone with healthy political ambition; you don't want someone too prone to hubris. No, I don't really know how to judge that.
5. And, yeah, you probably want to avoid a Nixon-style hater. If you can figure it out, and separate it from health ambition and from partisanship. Good luck with that.
