Mattis cited a Lincoln speech that ends with the explanation of why bipartisanship is so far from possible with the current Dem Mob ruling by passion and ignorance—they want nothing in common with, want nothing to do with our founding, except to undermine and uproot it entirely, then desecrate it completely.
Speaking of those who fought the Revolution, Lincoln closes with these words:
They were the pillars of the temple of liberty; and now, that they have crumbled away, that temple must fall, unless we, their descendants, supply their places with other pillars, hewn from the solid quarry of sober reason. Passion has helped us; but can do so no more. It will in future be our enemy. Reason, cold, calculating, unimpassioned reason, must furnish all the materials for our future support and defence.--Let those materials be moulded into general intelligence, sound morality, and in particular, a reverence for the constitution and laws: and, that we improved to the last; that we remained free to the last; that we revered his name to the last; that, during his long sleep, we permitted no hostile foot to pass over or desecrate his resting place; shall be that which to learn the last trump shall awaken our WASHINGTON.
Upon these let the proud fabric of freedom rest, as the rock of its basis; and as truly as has been said of the only greater institution, "the gates of hell shall not prevail against it."
