to correlate everything a president does with support of his general fan base is ridiculous. that's like saying democrats support murdering people with drones because Obama used that often. This type of logic is very divisive and dangerous.
Perhaps you're saying most Obama voters didn't like the drone killing but tolerated it because they liked the rest of Obama enough? That at least means they don't mind killing too much - it's not a show stopper for them.
In other words, it's not that this particular issue is a discriminator between candidates.
For example, one candidate is racist and thinks segregation and separate-but-equal is the way to go towards a peaceful society. The other one supports drone strikes (or something else you find vile). Any other candidates have one similarly vile views.
Abstaining from voting to protest these views doesn't seem to be the answer for most folks, so they look at other things and pick the one they like the most. Afterwards, you can voice your concern over the things you disagree with or choose to ignore them.
This isn't dissimilar to not needing to agree with everything your friends, partner, or family says to spend time with them.
So many people on HN seem to support strong climate change action, dislike drone strikes, and want massive immigration reform. But hardly anyone voted for the Green party.
The system in the states is a multi-party system in name only: Functionally, it is a two-party system, hence the low participation in such political parties. I think this could be changed with proper legislation, but am doubtful this will happen in the current political climate.
Besides, it isn't like the green party could make everyone happy either, and doubt they'd have an easier time getting things done in congress.
After WW2, immigration dropped, while a lot of new work in all areas was popping up. Result - labour shortages and decent wages, more or less.
