ALL five of the Hunter's state ALP members could lose their seats next year if the 25 per cent swing in Saturday's Penrith byelection is repeated at the March 2010 general election.
Minister for the Hunter Jodi McKay has the second smallest margin of any Labor member in NSW, holding the Newcastle electorate by just 1.2 per cent of the two-party preferred vote.
Maitland's Frank Terenzini has a 2 per cent margin, followed by Charlestown's Matthew Morris on 7 per cent, Swansea's Robert Coombs on 10.8 per cent, Cessnock's Kerry Hickey on 12.4 per cent and Wallsend's Sonia Hornery on 15.8 per cent.
Liberal MP Craig Baumann holds Port Stephens by 0.09 per cent, while Independent Greg Piper holds Lake Macquarie by 0.14 per cent. Both are tipped to increase their majorities.
Even a swing half the size of Saturday's would wipe out all of Labor's Hunter MPs except Ms Hornery.
