Pleasantly conversational, even on difficult issues, such as abortion and his personal failings. Articulate heralding the free market, but still short of specifics on spending cuts. Might come off as too New York for Iowans, but, as the mayor himself points out, his candidacy is not based on winning (or even showing) in the January 3 caucuses. Probably didn't boost his Iowa standing but didn't hurt himself nationally.
