Buttons showing the likeness of Republican presidential candidate, former Massachusetts Gov. Mitt Romney, are seen at a vendor stand outside a Romney campaign event at an oil company in Milwaukee, Monday, April 2, 2012.

Our take: Mitt Romney's religion has been one of the most scrutinized aspects of his presidential campaign, but could he use it to his advantage? The National Journal thinks so.

There are a few things Mitt Romney doesn't like to talk much about on the campaign trail.

One is his wealth, which, when he slips it into casual conversation on the trail like remarking that a few of his friends own NASCAR teams tends to get him into hot water.

And another is his Mormon religion, which Romney has shied away from mentioning. The religion raises more questions than answers for some voters, and a poll taken last year revealed only 45 percent of voters had a favorable opinion of Mormonism, with 32 percent viewing it unfavorably.
