If the border and humane treatment of other human beings is your jam, you don't need Kamala's border policy. Take everything you know about trumpty plumpty and Kamala and compare and contrast.
If you want a border policy that will bend towards justice and treat people more humanely, which candidate do you vote for?
If you want immigrants to be used as political pawns and want cruelty, which candidate do you vote for?
It's as simple as that.
If you need a "written policy" so that you can run an ideological purity test before you choose, then you are just a fucking contrarian.
