The Massachusetts experience, as well as the California experience, demonstrates why the GOP will die given the route it has chosen. The experience in those states also doesn’t give much hope a competitive alternative conservative third party can be created on the national stage. The cost of running campaigns is too high for a third party, funded by average citizens, to overcome. That’s why Obama walked away from federal financing of campaigns in 2008 in order to pursue unlimited campaign contributions.
I suspect going forward the GOP will have great difficulty raising money. Wall Street backed Romney but learned its lesson and will go back to being reliably Democrat. The pressure put on the Koch brothers tells independently wealthy people who have business interests not to venture into supporting conservative politics. Business people who have any dealings with government or whose businesses are in any way regulated know giving to conservative causes opens their organizations up to attack from the media, bureaucrats, and liberal judges. Over the next few years the Democrats will use their power to cut off funding for the opposition.
The Republican Party is voluntarily committing suicide by walking away from its base and capitulating on every issue. We are headed toward one party rule with a token opposition party controlled by the dominant party.
Which could produce all that is needed for a second revolt.
