It wasn’t to the Protestants, who have only voted democrat 3 times, 1932, 1936, and 1964.
The Catholic vote is democrat, but not because of boomers.
More Catholics voted Republican or did not vote at all than Catholics who voted Democrat so what ever point you are trying to make cannot be statistically demonstrated.
It is a fact that women overwhelmingly vote democrat in percentages exceeded only by black voters. Do you share an equal disdain for women and blacks as you apparently do for Catholics?
