From the leftist article itself
“”” If the margin of about 0.6 percentage points holds, Trump would be granted a recount, but his campaign would have to pay in advance to cover the cost of it. A statewide recount would cost millions of dollars, but Trump could try to limit the costs by conducting a recount only in certain places, such as Milwaukee County. “””
As I said, there is no automatic recount law in Wisconsin.
If the margin in less than 1%, either side may request a recount. If the margin is greater than 0.25% then the requestor must pay the costs of the recount.
Some states have laws where recounts occur automatically if the margin is below a certain percentage. Wisconsin does not.
