Answer 1

Liberal is the answer.

Answer 2

I believe the answer is: Liberal.
In general, citizens that had a liberal view of politics tend to favour more government intervention in their day to day life.
So they tend to support things such as higher taxes, more Government welfare programs, more government budget allocated to public education, etc.
