Liberals will do what they do best: bankrupt the moral climate, raise taxes, attempt to institute Erebusic social programs, and emasculate our military.
"Erebusic" is not a word (the dictionary tells us so). Massie is presumably referring to Erebus, a mythological creature who is the "embodiment of primordial darkness" and is "used metaphorically for Hades itself." What Massie appears to be saying is that Democratic social programs (he doesn't name which ones) will create hell on earth.
This is what passes for thoughtful conservative commentary at WorldNetDaily.
