Problem is that with politics people vote for what is most important to them right now.

Yes 3 years ago they could have been screaming at the same government over issue B, but right now there most important issue A is what they are supporting.

And that is another thing, prioritisation. Not only do people have to care about something, but it is horse trading. They will have to have it as one of their top 5 issues and in a close race where the contenders are similar in a lot of issues, then the voters have to have anti-abortion as number 1 otherwise another issue will swamp it.

Imaginary Voter:
List of priorities

1) Tax cut in half for his pay bracket.
2) Increase in the Surge and better body armour for troops.
3) Better servers and access for all to the Org.
4) Higher literacy rates for young children.
5) Anti-abortion

If two options are held before him at the elections and the first one is:
1) Yes
2) Yes,
3) Yes,
4) Yes,
5) No
vs option two.
1) No,
2) Yes,
3) Yes,
4) Yes,
5) Yes.

His priorities place 1) as number one, everything is secondary. So he ends up voting for his tax cuts and hoping one day to get a 5 x Y.
