Stanley Kurtz has done his homework. The copious notes attest to that. The Left will hate this book. They will do best to ignore it because it is beyond refute.
The message is two fold. The first is Obama is a Socialist, capital S. The second message is cause for even greater concern. It’s the message of stealth, gradualism and determination; first and foremost is stealth. 
“The American people will never knowingly adopt socialism, but under the name of liberalism they will adopt every fragment of the socialist program until one day America will be a socialist nation without ever knowing how it happened.”
– Norman Thomas, the once perennial presidential candidate of the American Socialist Party
The hope is the nation will not awake to the reality until it is too late. Obama’s strength is his stealth. Without it, the highest office he could have attained is State Senator within the Illinois government.
Kurtz concludes the book,
“From his teenage years under the mentorship of Frank Marshall Davis, to his socialist days at Occidental College, to his life-transforming encounters at New York’s Socialist Scholars Conferences, to his immersion in the stealthily socialist community organizing networks of Chicago, Barack Obama has lived in a thoroughly socialist world.”
and
“In sum, the fears of Obama’s harshest critics are justified. The president of the United States is a socialist.”
