At the 1715 general election Drake was returned as Member of Parliament for Tavistock jointly on his own and the Bedford interest. He was returned unopposed at Tavistock in 1722 and 1727. He was also returned in 1727 for Bere Alston where the family controlled one seat, but chose to sit for Tavistock. The new Duke of Bedford did not support him at Tavistock at the 1734 general election and he was defeated. However, he was returned for Bere Alston again and took his seat there until his death.
