Bristol Palin -- Stalker Says, 'I'm Moving In' ... And Here's My Coffee Pot

Bristol Palin has a deranged suitor who believes he's her son's daddy and wants to do the right thing ... by moving in with her.

Michael Cummings had a box and suitcase delivered to the P.O. box for Todd and Sarah Palin's Wasilla home, packed with his belongings, including a Keurig coffee machine.

He's been a thorn in Bristol's side for a long time, sending her an engagement ring, showing up at birthday parties and leaving a knife in her mailbox. She got protective orders in the past, but they've all expired.

So Bristol went back to court and got another one, ordering him to stay 1,000 feet clear of her and her family.

Here's the problem ... people who are mentally disturbed are the least likely to obey stay away orders. But it's the best Bristol can do, and at least if he violates it the cops will arrest him.
