Some of Gingrich’s support is from people who think he is more consistently conservative than he really is. His opponents are going to fix that. Some of his support is a kind of deal-with-the-devil to support him because they think he is invincible. But he isn’t ten foot tall. He is going into the next debates with very high expectations, opponents who are sharpening the knives, and a boatload of vulnerabilities. His position is far more fragile than his poll numbers would lead one to believe.
