It implies that either they themselves are even more reprehensible and irredeemable, or the majority of US voters are so morally bankrupt that they prefer reprehensible and irredeemable candidates. The latter is probably true, but why would they say that and then continue to run for elections? Why do they want the approval of morally bankrupt people who prefer reprehensible candidates?
