The Catholic vote

[TDAS04]

Catholics were mostly Democratic as a whole until the late 1900s, but there were a few exceptions:

*Before the New Deal, Italians and French Canadians were considerably more Republican than the Irish.

*During New Mexico's earliest elections as a state, the Hispanics appear to have been mostly Republican, and the Anglos mainly Democratic (NM Anglos were virtually Texans).

*An early Catholic group that possibly voted GOP during the 1800s might have been German Catholics in Missouri and Texas.  Germans in those states were pro-Union during the Civil War, (most of Lincoln's 1860 Missouri votes came from German immigrants).  However, I doubt that German Catholics provided the same support to the GOP that German Protestants did.

To answer the OP, Catholics will probably continue to vote fairly similar to the national average, as they have generally done since the 1970s.
