I think it’s a nice litmus-paper question.
Grudging charity, charity that comes bundled with a sermon, or charity that’s actually a trade of value for value is not really charity.
I happen to believe, though, that being a Good Samaritan is more likely to be a personal than a political trait. I think help can come from any quarter, no matter how unlikely. Absent any prior connection or claim (“We’re members of the same club, tribe, community, nationality”), it’s going to depend more on the character of the prospective helper, that helper’s own resources, and the fit of perceived need with perceived relief than on any political conviction.
Not that politics won’t play a part, seeing that politics is about who gets to control the resources; but it won’t be party politics.
One of the things I read right after Katrina was a first-hand essay by a survivor, who said that when resources (water in particular) were scarce, people were dangerously hostile in guarding their supplies; but as soon as there was a plentiful supply, people shared liberally with others in need. This stands to reason, doesn’t it? Perception seems to be the key.
Or I could have it all wrong. Oh, well.
