Not primarily, no. It points out the issues of life that no Catholic can support... ever. Then, it lays out the Democratic Party's support for each and every one of them. Rather than going candidate by candidate and issue by issue in all races (a book no one would sit through), the premise of the book is that all Democrats at all levels should be shunned until they, as a party, stop supporting evil. The purpose of the book is to get Catholic leadership to admit it and teach accordingly.
If the Democratic Party feared losing the Catholic vote (as much as 25% of the population by census), they would change in heartbeat. They can ignore our marches and rallies (and have for years) but they can't ignore us as a voting bloc if we start voting in accord with our Faith.
“...if we start voting in accord with our Faith.”
How many Christians (both sides) really have a Faith to vote in line with these days?
Most are cafeteria plan Christians, in denominations long infiltrated and indoctrinated by proggies (a very successful part of the Marxist-socialist plan initiated by The Frankfurt School and its adherents). I left ELCA for its leftist progressivism, and easily see it in many other denominations as well as in the RCC. Any World Council of Churches member is an apostate church:
