No that's just what they tell people they're about. They are for less federal government, but a huge military, less Government intervention in the free market, but huge corporate tax breaks and bailouts. Less Government intervention in their lives, but no gays or abortions. They're for bringing back the religious foundations of the nation, but don't know the founding fathers were mostly atheists and specifically wrote they didn't want a Christian nation. They're for less social safety nets, yet keep the military industrial complex which is a job's program. They're for a free and 'democratic' society, but draw maps to specifically circumvent democracy and make it harder for people to vote.Not really, they have been about less federal power, reduction of social programs, bringing back a more religious foundation, and less federal intervention in the market. For a good long time. Other aspects have shifted, but those fundamentals have been fairly consistent since the political shift happened.
The only thing you can say the Republicans have been consistent on is hypocrisy.
