The real betrayal of her constituents was in aligning herself with that party to begin with.
In her defense, she might be like Tulsi Gabbard and so many, from what I am seeing, dems and "left leaning" people in and out of politics. They all felt that they were standing in the same spot, and yesterday looked to their left and saw left leaning people standing a foot away. Today they look to their left, and there are screaching progressives a mile away yelling at them through a bullhorn about what fascists they are for still standing in the same spot.
It seems I am seeing this much, much more on the left than on the right. Of course on the right, as we have debated here in the past, we have never really been in lockstep and have always been bickering subgroups, for better or worse. The left has always been more prone to "lockstep", but with so much crazy antifa, transgender, abort at birth and for fun, and other whacko stuff, are starting to see people on their side say, "Wait a minute, this is nuts."
