Although an Ohio Senate seat would be vacated by the resignation of John Sherman to become Treasury Secretary, Hayes needed Garfield's expertise to protect him from the agenda of a hostile Congress, and asked him not to seek it. Garfield agreed. As Hayes's key legislator in the House, he gained considerable prestige and respect for his role there.[127] When Congress debated the Bland–Allison Act, to have the government purchase large quantities of silver and strike it into legal tender dollar coins, Garfield opposed it as a deviation from the gold standard; it was enacted over Hayes's veto in February 1878.[128]
In 1876, Garfield purchased the property in Mentor that reporters later dubbed Lawnfield, where he conducted the first successful front porch campaign for the presidency.[129] Hayes suggested that Garfield run for governor in 1879, seeing that as a road likely to take Garfield to the White House. Garfield preferred to seek election as a U.S. senator. Rivals were spoken of for the seat, such as Secretary Sherman, but he had presidential ambitions (for which he sought Garfield's support), and other candidates fell by the wayside.
