Andrew Little is wise to have ignored the pressure that was coming even from Labour quarters for him to pull his party's candidate from the Northland byelection in order to avoid splitting the Opposition party vote and instead boost Winston Peters' chances of winning the seat.
It is now too late to withdraw Willow-Jean Prime's nomination as Labour's candidate. Barring a candidate's death or sudden incapacity, a nomination cannot be pulled after noon on nomination day - which was yesterday.
Little may not have completely ruled out urging Labour-leaning voters to cast their vote in Peters' favour. Byelections can be unpredictable affairs. So it is sensible for Opposition parties not to foreclose on their options too early in the campaign.
But Opposition politicians also have to be realistic.
It would require everything to go spectacularly right for Peters and everything to go drastically wrong for John Key in the three or so weeks until polling day on March 28 for Peters to pull off a very unlikely victory.
