Oh, no! Is the Senate devolving into a fist-bumping zone? It sure seems so, given the display put on by Democrat Dianne Feinstein and Republican Kay Bailey Hutchison on CNN’s “Late Edition” Sunday. At the end of their segment, as host Wolf Blitzer was teasing the next segment, they reached across the table and, without prompting, bumped fists, a la Barack and Michelle Obama. That elicited a grin from Wolf, who suggested they do it again, this time with a wide shot of the moment.
