TONY Abbott and the Liberals have lost their three-year carbon tax advantage over Labor, with support for the Coalition dropping to its lowest since 2011 to leave the opposition leading on preferences for the first time since the election of the Gillard government.
Just three months after being elected, the Abbott government's primary vote support has dropped to 40 per cent while Labor's two-party-preferred support has jumped five percentage points to put the ALP in front 52 per cent to 48 per cent.
