Daniel studied law at the University of Virginia in Charlottesville, and he was admitted to the bar in 1866. He joined his father's practice at Lynchburg. Despite being crippled from his war injury, he enjoyed oratory, particularly memorializing the Confederate war effort and excoriating
Congressional Reconstruction and
Republicans. He entered politics and Campbell County voters elected him as a member of the
Conservative Party to represent (part-time) them alongside Rufus Murrell and
Robert C. Burkholder in the House of Delegates from 1869–72. He did not seek re-election. Daniel unsuccessfully sought nomination to the U.S. House of Representatives for
Virginia's 6th congressional district in 1872 and 1874, between which elections he canvassed for Conservative Party candidates in the state elections in 1873. The Funding Act which the legislature had passed in 1871 (although Daniel did not vote for it at the time) proved a major campaign issue in Virginia for the next decade. Daniel became one of its main supporters (known as "Funders"). Others, known as
Readjusters advocated reducing payments on the bonds issued in 1871 which reaffirmed the debts Virginia had acquired before the Civil War to construct railroads, bridges, etc. Although the bonds traded at far below face value, they could be used at face value to pay state taxes, so they significantly cut state tax revenues. Also, the interest rate was kept at the prewar level, which was much higher than postwar interest rates. In 1876, Daniel published his "A Treatise on the Law of Negotiable Instruments", which was reprinted several times. That year he also campaigned for
Samuel J. Tilden, the Democratic presidential candidate (who lost). However, Campbell county voters had elected Daniel to the state senate the previous year, and he was re-elected once before resigning the part-time position in 1881. In 1877, Daniel became one of the leading Conservative orators against the leading Readjuster candidate, former Confederate general turned railroad tycoon
William Mahone. Mahone ultimately withdrew his gubernatorial candidacy in favor of relatively unknown
Frederick W.M. Holliday of Winchester, Virginia, who was elected. Daniel was a
presidential elector in the
1876 presidential election. In 1880, Daniel spoke at the Democratic National Convention in Cincinnati, Ohio in favor of the candidacy of former Union General
Winfield Scott Hancock, whom he praised as offering the best hope for reconciliation between North and south. In 1881, Daniel was the Conservative Party's candidate for governor of Virginia, but lost by 12,000 votes (out of 211,000 cast) to
William E. Cameron, the candidate of a coalition of Republicans and Readjusters. During one state senate debate, Daniel had orated it "were better to burn the schools...than sustain them on money taken by force" from bondholders. In the 1883 Virginia statewide election year, race and cronyism within the Readjuster and Republican ranks became major issues. Although Daniel was not running for office directly that year, he and Mahone were the leading candidates for the U.S. Senate seat that the General Assembly would soon select. Daniel summarized the Democratic platform, "I am a Democrat because I am a white man and a Virginian." Democrats won control of the General Assembly, which was then allowed to reapportion legislative districts pursuant to the completed 1880 census. Daniel successfully defended the partisan redistricting in the
Supreme Court of Appeals over Republican challenge. He also benefited because Democrats nominated him as the 6th congressional district (as he had long sought), after popular incumbent
John Randolph Tucker was moved to the 10th congressional district. Daniel was a delegate to the
Virginia Constitutional Convention of 1901. He had advocated such a convention since 1895, and was elected as Campbell County's representative without opposition. At that convention, Daniel served on the suffrage committee and advocated requiring a voter to explain any section of the constitution, although some criticized his leadership. Future Senator
Carter Glass of Lynchburg developed a compromise involving a
poll tax and writing test which passed and became a means for disenfranchising African Americans and poor whites. ==Federal political career==
