The linked image reflects the nature of the late-Weimar political parties and their respective political strongholds in Germany. One of the most pervasive political parties of both Imperial Germany and Weimar was the German Catholic Centre Party. The Centre generally was a right-of center party that appealed to Catholic voters. Because of its Catholic base, it never could become a majority party in Germany, so it was dependent upon coalition partners. As the map shows, the Centre did best in areas with large Catholic populations such as Bavaria. In the aftermath of the Depression and the resulting political crisis, the Centre managed to retain a degree of political cohesiveness. Unfortunately, the same could not be said of other political parties. The Socialist Party (SPD) lost votes to the more radical Communist Party (KPD) and various the conservative parties could not match the dynamism of the NSDAP, although this did not prevent some on the right's leadership like von Papen (an exile from the Centre) and von Schleicher from thinking they could use Hitler for their own ends.

So in the elections of 1932 and 1933, the Centre campaigned quite intensively and achieved some results. The further fracturing of the established political parties and the mistaken belief of the German right that it could manages the NSDAP surge meant that Centre's holding onto their electoral territory came to naught.

The Centre's position after Hitler came to power was also somewhat chaotic, as was the overall position of political Catholicism within the Third Reich. Despite notable internal opposition, the Centre's leadership voted for the Enabling Act that granted Hitler broad sweeping powers. In the process of Gleichschaltung (coordination) the Third Reich sought to minimize or co-opt the various Catholic organizations that were the bedrock of much of the Centre's support. The German Concordat with the Papacy in July 1933, which gave Catholicism guarantees over its educational and youth organizations in exchange for not actively intervening in German politics, also made it much more difficult for the Centre Party to regroup in light of its loss of this support network.

As for the original question as to whether or not the Catholics supported Hitler, it is more difficult to answer. There is evidence for strong German Catholic support both for and against the regime. For example, Bavaria was not only one of the Centre's strongholds, but it was also the cradle of the NSDAP. While the Third Reich never really honored its commitments made in the Concordat, but it never really could control the German Catholic Church either.

The Center Party, the Catholic political party that's been around since 1870 were much more cohesive as a group than the other two big anti-nazi parties: the SPD (social democrats) and the KPD (communist party).

The short version is that they played the political game a bit better and longer than the other two. They dissolved themselves, before they could be banned by Hitler.

Lutherans, or protestants in general didn't have a cohesive group like that. But Hitler was opposed in all other parties, just not enough.

Catholics were interesting because Bishops (at first) spoke out against Hitler, and they had a political party to back them up.

I wouldn't read into that map too much, it's just showing that in non-catholic areas the resistance was too splintered and made a difference at the poles.

Also, a big factor is that Hitler tried to play nice with Zentrum. SPD and the KPD were socialists and therefor the enemy. Zentrum was the previous right (as is its successor the CDU is the current right.) So Hitler wasn't as harsh to Zentrum at first.

Zentrum actually made strides in the election in that picture. While the SPD and KPD lost votes (due partially to a lot of pressure from Nazis on the streets)

And after this election there were even talks between the NSDAP and Zentrum (which fell through) to form a coalition in the next election..so basically Zentrum was walking a fine line, and didn't realize how much they were playing with fire. But the Nazis weren't as worried about Zentrum votes as long as Hitler could get their voters into his coalition.

So basically, no, that picture is BS. Bavaria was one of the strongest bastions of Nazidom. The percentages here needed to create a picture like that are not really statistically significant, and have much more to do with Hitler's policies and how religion aligned with the political parties than religious breakdown!

That being said... every antisemitic book at the time written in German quoted Martin Luther.. propaganda's a bitch. There are a lot of factors that are not mentioned in those maps!
