Come to that, was Chase's?
Istr that in 1868 he was a contender for the Democratic nomination, which seems hardly compatible with being a radical reconstructionist.
Well, Chase may have been too ambitious for his own good (or at least his own reputation). "If S.P. Chase weren't in quite so big a hurry to be President, he would stand a much better chance."--Horace Greeley, 1858

In 1868, Chase might have sought the Republican nomination, but it was clear that the Republicans wanted Grant. OTOH, it seemed that he at least had a chance for the Democratic nomination: His conduct of Andrew Johnson's impeachment trial in the Senate had endeared Chase to many Democrats, and he was also beginning to become disillusioned with military Reconstruction. Chase summarized his own position on Reconstruction in 1868: "Congress was right in not limiting, by its reconstruction acts, the right of
suffrage to whites; but wrong in the exclusion from suffrage of certain classes of citizens and all unable to take its prescribed retrospective oath, and wrong also in the establishment of despotic military governments for the States and in authorizing military commissions for the trial of civilians in time of peace. There should have been as little military government as possible; no military commissions; no classes excluded from suffrage; and no oath except one of faithful obedience and support to the Constitution and laws, and of sincere attachment to the constitutional Government of the United States."

Anyway, this position was not really acceptable to either party in 1868. The most obvious problem in getting the Democratic nomination was stated by Chase himself: "it has seemed to me well nigh impossible to get over the difficulty induced by the almost universal commitment of the party to hostility to the colored people."
