Neither the Republicans nor the Democrats support the views they claim to. Those are just ways to get votes from their gullible and emotionally persuadable constituents who will pick the least-worst of the 2 choices as long as the candidate of their choice presents a veneer of authenticity.

Politicians really support the views of the people who actually matter to them - the donors who fund their campaigns, the lobbyists who give them nice perks while they're in office, and the companies who promise them high-paying jobs once they've left public office.
