Since about 50-55% of eligible voters actually vote in US general elections, they are suggestive of general apathy among those enfranchised. If you have a better club to wield, do so Metaphor
It's quite simple. Toni thinks Republicans are morally bankrupt and utterly shameless.
Gallup shows that 30% of Americans call themselves Republicans:

By this standard, about 30% of the population surveyed by Gallup are Republican. (Like any sane person, Gallup does not ask children, who cannot vote, what their political affiliation is).
If you scroll down that link, it shows that Independents can be self-described as 'Republican leaning', 'Democrat leaning' or neither.
If we look at this figure for Republican + Republican leaning (46%), we can assume that 30% of the population is morally bankrupt and utterly shameless, and an additional 16% of the population is morally bankrupt and utterly shameless adjacent.
As for Trump, 49% of adults in the US approve of his performance, so I assume all these people are also morally bankrupt and utterly shameless.
