There are two name attributes having the same value animation.

<input type="file" name="animation">

and

<input class="file-path validate" id="animation" name="animation" type="text">

The second name attribute is overriding the first one. You need to give it a different name.

Change your Ajax code :

$("#update_politic_btn").click(function(event) {
var chango = new FormData($("#update_form")[0]);
// try this if above one not work
//var chango = new FormData($("#update_form"));
$.ajax({
    url: baseurl + 'admin/update_politic',
    type: 'POST',
    data: chango,
    async: false,
    success: function (data) {
        console.log(data);
        list_politic();
    },
    cache: false,
    contentType: false,
    processData: false,
    error : function() {

    }
});
event.preventDefault();
});
