The last known photograph of Cleveland by Underwood & Underwood (1907)
In 1906, a group of New Jersey Democrats promoted Cleveland as a possible candidate for the United States Senate. The incumbent, John F. Dryden, was not seeking re-election, and some Democrats felt that the former president could attract the votes of some disaffected Republican legislators who might be drawn to Cleveland's statesmanship and conservatism.[264]

Death
Cleveland's health had been declining for several years, and in the autumn of 1907 he fell seriously ill.[265] In 1908, he suffered a heart attack and died on June 24 at age 71 in his Princeton residence.[265][266] His last words were, "I have tried so hard to do right."[267] He is buried in the Princeton Cemetery of the Nassau Presbyterian Church.[268]

Honors and memorials
In his first term in office, Cleveland sought a summer house to escape the heat and smells of Washington, D.C., near enough the capital. He secretly bought a farmhouse, Oak View (or Oak Hill), in a rural upland part of the District of Columbia, in 1886, and remodeled it into a Queen Anne style summer estate.
