Andy Little, Lee Wallace, David Templeton and Bilel Mohsni were also on the scoresheet as the home side turned on the style to post their ninth consecutive win in all competitions.
The returning Ian Black set up Daly to head the opener at Ibrox on Saturday and when an attempted clearance fell into his path, the former Dundee United man bagged his second.
Sections of the Ibrox support were on their feet as chants of 'sack the board' rang around the stadium, the spectre of off-field strife continuing to haunt the Govan-based club.
Rangers claimed their third of the day after 37 minutes when Kevin McKinlay's attempted clearance went in off Little and when Daly got on the end of Richard Foster's long punt with a diving header it was 4-0.
Wallace was set up by Black for the fifth and, with the Warriors tiring, Daly (82) helped himself to his fourth after good work by Nicky Clark.
Substitute Templeton came off the bench to get in on the act and Mohsni completed the rout in injury time with the goal of the game - a fine overhead kick.
