The Constitution Party, who had Castle as their candidate (BW stated she voted for Castle), holds as the first of their seven principles that life from conception is sacred.You vote turned its back on the unborn. You're right, that belongs to you.
She voted for a pro-life candidate. Thus, your accusation is false, and you owe her an apology.
Of course, you'll come back with some stupidity about how voting for a third-party candidate was a wasted vote, and supported Hillary; but just I've already answered Yeshua, Hillary, Sanders, and Obama all thought that voting third-party was a vote for Trump.
And since Trump won, guess what? They were right. By taking a vote away from Hillary, BW helped Trump get elected.
Don't do a knee-jerk response; chew on that thought for a few minutes, take it around the block for a spin.
