Mitt Romney made another mistake last week trying to inflate his record as a hunter, and he's paying the price. Pat Bagley took advantage of the goof with this cartoon in the Salt Lake Tribune:

Romney rival Mike Huckabee also went to town, responding to a direct question about the episode from Bob Schieffer on Face the Nation yesterday (video):

"It'd be like me saying I was a lifelong golfer because I played putt-putt when I was 9 years old and I rode in a golf cart a couple of times."

And in the latest edition of Newsweek, Evan Thomas, Samantha Henig and Jonathan Darman write that Romney's efforts to explain the stumble came off as "stiff and lame - one more example of Romney's trying to pander to true-blue conservatives and getting called out for it."

The hunting flap is a perfect example of the aggregation effect in politics; a small, rather insignificant mistake in isolation, but one that takes on much greater significance when added to a growing list of previous mistakes that all raise the same question about Romney and reinforce his biggest negative as a candidate, which is that he sometimes comes across to Republican voters as inauthentic on certain issues.

How many more mistakes like this can Romney endure? Your guess is as good as mine. One hundred million dollars (or whatever Romney is on pace to raise) will help paper over a lot. But at some point if Romney's missteps continue, the doubts they raise in the minds of Republican primary voters will reach a critical mass - and that's a problem all the money in the world won't solve.
