Catholics have voted almost entirely democrat since they arrived in America, but as far as the last 2 elections, they voted republican in 2004.
Catholics voted against an incumbent democrat once(1980).
2004 they just barely went Republican. The biggest gains in White Catholics. I think that goes along with what I saw in NM with the Hispanic, Democrat, Catholic population. Probably higher in the union regions too.
It seems that they might swing against the incumbent democrat this time; they swing for economic reasons.
YOU said that Catholics....only you said catholics, which tells me something about you....voted for dems until 2004!!!! PROJECTION!
