The key mantra about Get Out The Vote is that the battle is mostly won in the long campaign.
The key technique is to get a voter to make an emotional commitment to voting by talking personally to an actual human being (think Asda/Walmart having someone greet you on entrance - it works).
Weakly identifying voters (switchers, intermittent voters) are preferentially contacted by the candidate, other more grounded ones get ordinary party members on their doorsteps, plus personal letters etc.
So this failure is likely symptomatic of a general failure of GOTV planning - which means the polls are likely to be correct.

There is no magic polling day bullet.
