Bunk
If Hillary wins she will be a centrist, or a bit left of center, and a pragmatist - the way she has lived her life, political and otherwise.
However, it won't make any difference to many here - as she will be as excoriated by the far-right as George Bush is by the far-left, and the mature discourse and accepting of compromise - upon which the country was founded - won't be there on either end of the spectrum.
As far as gun-control: it will not be a major item on her agenda, as it would not for most pragmatists - though she may try to increase Federal oversight of illegal traffic - (good -as that has nothing to do with 2nd A.).
For the vast majority of the population that is not rabid leftist, or rabid rightist, she will likely be considered either pretty good with a plurality of issues, while lacking in some - or considered not especially effective for some issues, while adept at a smaller number.
Nothing she does will be liked by the extreme rt wing, and she will be followed by another centrist, slightly to the right, and whoever that is will be immensely unpopular with the far-lft.
