Conservatism ultimately wins elections

In 2012 we have yet another election year that is primarily a reaction against the establishment, and the country has swung back and forth yet again, unhappy with both parties. But why?
 
The problem with George W. Bush was not that he was conservative, but that he was not conservative enough — he hurt the credibility of the GOP by bloating the government further, and not just the military and the Department of Homeland Security, but, in his "compassionate" conservatism, blowing money on domestic spending as well.
 
If the Republicans stick to constitutional and classical liberal principles, they win elections. They got drunk with power after Gingrich took over in 1994, and didn't deliver on their promises. Since then, they have collectively failed to practice what they preach. The worst of their transgressions was the Medicare Part D entitlement that now-Speaker Boehner and President Bush added, worth around $13 trillion in unfunded dollars, hoping to bribe their way to a permanent majority.
