Is michele bachmann a Nazi

Not by any stretch of imagination.

She is, however, a very Right-wing Conservative, who follows a rather radical form of Evangelical Lutheranism.

None of her economic policies share any commonality with Nazi-ism (though, frankly, Nazi-ism wasn't really strong on economic theory) - rather, she espouses a very laissez-faire form of capitalism.

However, on social matters, she does hold (and proclaim) some rather intolerant views; it is that level of intolerance, rather than the actual substance of those views, that some use the hyperbole comparison to Nazi-ism.
