Hobart, like some other members of his family, cultivated ‘pretty ladies’, an affected style, and went in for theatricals. In April 1786, when a vacancy was expected at Lincoln, the Duke of Rutland recommended him to Pitt;
But if ... on a vacancy he should find himself disengaged, let him know that Major Hobart will have my utmost support, and that I am certain I shall have his. I hope Mr. Pitt, on all my election views, will not contend to prevent my ability of serving him.
On 15 Dec. 1788 Hobart was returned for Bramber on the Rutland interest, and on 16 Dec., in the division on the Regency bill, voted with Government.
He died 4 Feb. 1816.
