The Presidential Contest.

The impending radical contest for power has already assumed the magnitude of an "irrepressible conflict." One year ago today the dominant party swayed with defiance the scepter of an united political organization. It declared against the agitation of political measures, incompatible with the purposes of the administration. Public journals were suppressed; statesmen imprisoned and driven into exile; and the most vital provisions of the constitution suspended. Time passed on. The principles of the democratic party became essential to the salvation of the government. Those that were foremost in denunciations, are now first to embrace the war policy of the democratic part. The union in the republican party is broken. This is natural and logical. The union which they contend carried discord and confusion into the council of the nation. It was Union with no harmony. It agreed with regard to offices, but disagreed with regard to principles. Some of its leading members have avowed the most extreme doctrine of the secessionists. Others agree with the abolitionists.

Controvercies began with their advent to power. Now, which shall triumph? Lincoln and Fremont are in the van. The former has to bear the burdens of his administration, with its unaccountable array of corrupt and unconstitutional measures. The latter can consistently repudiate them, and enter the field a constitutional candidate. They have raised the demon that will not down at their issues; they are disunited. Can fat jobs, contracts, and promotions to office unite them? This will be decided at the Baltimore Convention. — This contest on the part of those who pretend to administer this government may bring damaging disasters to the nation. — Their cause will demand a vigorous prolongation of the war, at whatever cost of blood and treasure.

Lincoln will be nominated at Baltimore upon a radical platform. Those who make the object of the war the abolition of slavery, and the men who desire peace or the dissolution of the Union, will support Lincoln as the man upon whose election depends the accomplishment of their respective purposes.

The conservatives, who are for putting down the rebellion and restoring the Union and the constitution, indifferent as to slavery, will support the candidate opposed to Lincoln. All factions having destructive and reckless theories will be driven to one side, and the calm conservative portion of the people to the other. The radicals, like Haman, they are destined to hang up on the same gallows they had builded for others.

We find the probable state of parties in the coming contest clearly and truthfully stated by Geo. D. Prentice, of the Louisville Journal. He says:

There are, as we beg to repeat, but two great parties in the country, namely, the conservative party, and the radical party. The basis of the radical party is universal and immediate emancipation by the general government, and the prosecution of the war until this end is secured. The basis of the conservative party is the constitution, and the prosecution of the war until the supremacy of the constitution is acknowledged. The latter is a constitutional party; the former is a revolutionary party. The conservative party would maintain the government as our fathers made it. The radical party would subvert the government and construct a new one according to the radical eagaries. Such are the respective bases of the two great parties of the country.
