The Ryan plan is not a conservative budget in the true sense of the term. If it were it would cut government spending across the board, not give a free ride to wasteful Pentagon spending while letting other programs bear the full burden of spending reductions.
It's easy to attack and demagogue those who don't have a voice. It's easy to blame others when you fail to provide true leadership. And it's easy to reinforce stereotypes and misconceptions to win elections, or to win over your party's base. That is precisely what Paul Ryan did last week.
There would seem to be no one in the upper echelon of Republican circles who is strong and influential enough to dissuade a flawed wannabe. It appears unlikely, then, that anyone will tell Paul Ryan to cancel his dreams.
