What Anti-Catholicism?

The priest in this postcard is wearing an "ignore the poor" button. It's being sent by Minnesota DFL (Democrat-Farm-Labor) party. This is their mailing for campaign season. Their website says:
The Minnesota DFL supports and works to enact the ideals and principles of the Democratic Party and strives to sustain the foundations in our Party’s grassroots history.
Ah, the Know-Nothing grassroots!

(This is rank bigotry --why don't they just cartoon Catholics as rats and have them driven into the sewers? But I have to ask what their complaint can possibly be. Dollars to donuts whatever economic program they're pushing the local bishop also supports.)

Curtsy: Matt Archbold

Update: As I expected, their beef is in favor of Obamacare, which the American bishops support in principle --they just want the abortion funding and conscience crushing out. And the guy they're running this ad against is an evangelical preacher. Apparently no matter who or what your position is, it's always safe to make a dig at the Cat'lics.
