Sarah Palin believes her TWO jailed stalkers are still very much a threat ... and she's begging an Alaska judge to extend the restraining orders against them for another 6 months.
TMZ broke the story ... Shawn and Craig Christy, a father and son duo from Pennsylvania, were locked up in Alaska back in August for allegedly threatening to kill Sarah, her family and her friends.
Sarah had obtained restraining orders against the men ... but they were only temporary and will expire in November.
But Sarah has launched a preemptive strike ... filing a formal request to extend the order into 2012.
Sources connected to the case tell us ... the men are still waiting for their trial ... and will remain behind bars until a court date is scheduled.
If Sarah's request is granted, the men will be barred from having any contact with the Palins in the event that they are released.
A judge is expected to rule on Sarah's request sometime within the next few weeks.
