Colin Craig was on TVNZ's Q+A this morning, and was complimented for his improved performance by members of the panel. I don't buy it.
But as I've said here a number of times, if John Key wants a third term, National needs allies. Act is stuffed, regardless of whether John Banks can successfully defend the charges against him. Peter Dunne's UnitedFuture are too small to break out of Ohariu. Whether the Maori Party can survive without Tariana and Pita is an open question (IMHO their seats will go back to Labour). Most National supporters remember the 1996-1998 coalition disaster and couldn't stomach another NZ First coalition.
Colin Craig, while being a troglodyte social conservative, is still John Key's best bet for a third term.
