to prohibit the spread of slavery into the
Territories, has no constitutional power to do so. Not only so, but
that decision lays down principles which, if pushed to their logical
conclusion,--I say pushed to their logical conclusion,--would decide
that the constitutions of free States, forbidding slavery, are themselves
unconstitutional. Mark me, I do not say the judges said this, and let
no man say I affirm the judges used these words; but I only say it is my
opinion that what they did say, if pressed to its logical conclusion, will
inevitably result thus.

Looking at these things, the Republican party, as I understand its
principles and policy, believes that there is great danger of the
institution of slavery being spread out and extended until it is
ultimately made alike lawful in all the States of this Union; so
believing, to prevent that incidental and ultimate consummation is the
original and chief purpose of the Republican organization. I say "chief
purpose" of the Republican organization; for it is certainly true that if
the National House shall fall into the hands of the Republicans, they will
have to attend to all the other matters of national house-keeping, as well
as this. The chief and real purpose of the Republican party is eminently
conservative. It proposes nothing save and except to restore this
government to its original tone in regard to this element of slavery, and
there to maintain it, looking for no further change in reference to it
than that which the original framers of the Government themselves expected
and looked forward to.

The chief danger to this purpose of the Republican party is not just now
the revival of the African slave trade, or the passage of a Congressional
slave code, or the declaring of a second Dred Scott decision, making
slavery lawful in all the States. These are not pressing us just now. They
are not quite ready yet. The authors of these measures know that we are
too strong for them; but they will be upon us in due time, and we will be
grappling with them hand to hand, if they are not now headed off. They are
not now the chief danger to the purpose of the Republican organization;
but the most imminent danger that now threatens that purpose is that
insidious Douglas popular sovereignty. This is the miner and sapper. While
it does not propose to revive the African slave trade, nor to pass a slave
code, nor to make a second Dred Scott decision, it is preparing us for the
