Then I assume you won't have any trouble pointing to some of those Northern States' congressional representatives making that clear, right?
The fact is that about a full 25% of the Army was on the Texas frontier in the decade before secession, vastly larger, proportionately, than the percentage of the armed forces in Iraq at the height of the surge.
Douglas had been a viable future presidential candidate when he helped engineer the 1850 Compromise, but his political career was utterly destroyed by the slavery issue and Kansas-Nebraska. Kansas-Nebraska was his effort to straddle and finesse the slavery issue being pushed by Free Soilers and Northern Whigs. Lincoln not only unhorsed Douglas but wrecked his party with the slavery issue.
You are aware, right, that Lincoln lost to Douglas in the 1858 senate race, four years after you say his political career was "utterly destroyed" by the Kansas-Nebraska Act?
The Republican Party was founded as a direct response to the Kansas-Nebraska Act. Lincoln re-entered politics after many years in private life as another direct response.
So Douglass’ attempt to suck up to the slaveocrats created his own nemesis.
