I’m against these tactics no matter who uses them. I’m also against the mailings that respond selectively to known hot buttons of the targeted recipients. While omitting facts that reveal the candidate or PAC is taking positions opposite to their targets, they only reveal the positions where the two are in agreement. They are hoping the targets won’t realize their money will be used to fund activities they are against, as well as those they support.
It seems today most political discussions descend into shouting matches of accusations and personal attacks rather than rational discussions of policy differences and how they would affect people.
