Most Catholics have come from economically poor backgrounds.
In the past they voted democrat because they felt that party represented the working man.
However the democrat party has been taken over by the socialists/communists.
A lot of democrat voters don't realize this and continue to vote for the democrat.
The democrat Ronald Reagan hit the nail on the head when he said -I didn't leave my party, they left me.
The cowardly Republican politicians won't call them socialists, and continue the deception by calling them democrats.
The same is true of most of the right wing talk show hosts. -Tom
This is a misconception. Gallup did an extensive study on American Catholics (or those who identify as Catholic, anyway) and found that Catholics the nation's average in virtually every economic and education Category. About the only way that Catholics as a group differ from society in general is that they are more Hispanic (29% versus 13%) and less black (3% versus 11%) than the nation at large.
