I find it hard to agree with anyone that says the country has gotten more right over the last 20-30 years. That's a ridiculous statement. EVERYTHING the right stands against has been growing: entitlement programs, welfare programs, size of government, the debt, record number of regulations on employers and business, individual tax burdens, underemployment, etc.
Whereas things the right typically stand for have been shrinking: individual freedoms, free market economy, Capitalism, Defense is getting pushed out by more popular spending programs, etc.
Things like 'gay rights' wasn't a huge step forward for society, it was a push to get more people onto a government program subsidized by the taxpayer (marriage). People saying that the country has gotten more right are just ignoring, or selectively interpreting, the facts.
