This seems like complete rumor, gossip, and conjecture (I mean, the fucking article cites the National Inquirer for Christ’s sake), but at any rate, here it is:

AlaskaReport has learned this morning that Todd Palin and former Alaska governor Sarah Palin are to divorce. Multiple sources in Wasilla and Anchorage have confirmed the news.

A National Enquirer story exposing previous affairs on both sides led to a deterioration of their marriage and the stress from that led to Palin’s resignation as governor of Alaska.
