I have no interest in voting for a libertarian-leaning candidate
That's good because Weld isn't one.
How so? Isn't he was generally regarded as a 'downsize the government' conservative with socially liberal leanings? Explicitly professing a libertarian ideology isn't what I mean by libertarian-leaning.
Except he didn't downsize government at all. He cut it by a measly 1.8% his first year then subsequently increased the budget roughly 17% by 1994. And social liberalism more often than not is the anti-thesis of libertarianism, there is nothing libertarian about affirmative action, gun control or special protections for gays for example. All of which of course Weld supported.
Well, if only there were more Republicans like Bill Weld.
