In her own way she's been trying to carve out what she views as a sensible, governable political "center".  She's certainly not where I am on economic policy but has moved away sharply from current GOP orthodoxy on those as well as on many other issues.  She conveys a willingness to change her mind when the facts call for this, without coming off as in the least bit mealy-mouthed, as E.J. Dionne, Jr. sometimes does to me.  She'll call out supposed GOP moderates like Susan Collins when they wilt, as on the tax legislation just passed, and praise GOP figures when they do something positive for a change.  And she'll call BS where she sees it, as when Rubio "held out" for some modification of the child care tax credit when insiders knew there was not a chance in hell he was going to vote no, no matter whether they offered him anything more than a fig leaf.  She's been just as relentless calling out the GOP Congress and its leadership as she has been with calling out the Trump Administration, all with just the facts.  She even called out Sessions the other day for (further) setting the GOP back with millennials with his attempts to up federal enforcement of marijuana laws contrary to the laws of many states that have liberalized their laws. 

If I compare her to perhaps the leading Democratic establishment opinion writer, Dionne, I observe she has been consistently more pointed and forceful, more prolific, and has not been the least reluctant to suggest specific courses of action or angles to advance the Trump-Russia investigation.
