NY Times Write Up
It's an interesting read. Two points of contention though.
First, Walsh brought up the infamous infant hearing screening which he used in an ad last year, and cited it as an example of how he can work while in the minority. One problem, its just not true. Not only did Walsh's bill never pass, the last 3 times he sponsored it was while there was a Republican Majority, and when a similar bill did pass, it was authored by another Republican.
Second, if this is him raising money like mad, he's going to be easier to beat than I thought.
