May I say, Boudicca, you have a gift with words. Okay, so you found it, but it sure does fit! Obola, the destructive, national contagion that keeps on spreading. Not spreading fast enough? No problem. Bring in more immigrants & middle eastern refugees.
This is, of course, not minimizing the suffering & deaths from Ebola. The left doesn't like this at all.
In my opinion, it is referring to the spread of progressivism, which is a destroyer of American values & our Constitution.
& after he leaves office? The contagion will continue, via a job for O as a powerful lobbyist, or king of the community agitators.
