In 1863, he re-entered politics, being elected to the United States House of Representatives that year. He succeeded in gaining re-election every two years up through 1878.
Looks like he ran for the Senate but his seat was taken by Sherman. He was elected President in 1880, so with a two year gap, he went from the House to the White House.
Who? Garfield like Torie offered?
Yep, and GHWB went from U.S. Congressman for the 7th District of Texas to U.S. Amb. to the U.N. from 1971-1973.

Garfield is the only person who was elected president directly from the United States House of Representatives.
