Charles Homans at The Washington Monthly explains:
There was talk of her (Palin) taking Stevens's place on the Republican ticket in the general election if Stevens is found guilty, and it's probable she would have beaten Begich (the Democratic contender) --so this is good news for Democrats in the Senate. Parnell, (current Alaska Lt. Governor, waiting a recount in last Tuesday's Republican primary against Don Young for the sole Congressional seat in Alaska.) meanwhile, would presumably take over as governor if McCain/Palin wins.This looks like all kinds of fun breaking out in Alaska.
