Hay was returned for Seaford by the Duke of Newcastle, his cousin by marriage, on whose behalf he canvassed energetically at Sussex elections. In spite of physical disabilities - he was a hunchbacked dwarf - he took an active part in the Commons, where he voted with the Government in every recorded division. Making his first reported speech against an opposition place bill in Feb. 1734, he spoke for the Government on the army in 1735, when he published a criticism of the poor law, stating that
every parish is in a state of expensive war with all the rest of the nation, regards the poor of all other places as aliens, and cares not what becomes of them if it can but banish them from its own society. No good therefore is ever to be expected till parochial interest and settlements are destroyed, till the poor are taken out of the hands of the overseers and put under the management of persons wiser and more disinterested, and till they be set to work on a national, or at least a provincial fund, to arise from benefactions and the labour of the poor, as far as they will go, and what more is wanting to be levied by an equal tax.
In 1736 and 1737 he introduced bills for implementing his proposals, but failed to carry them through the House.
