First, Romney gets lambasted as a lackluster, wishy-washy candidate
Second, the Far Right and Religious Right blame his loss on a Romney's lack of ideological purity. (NOTE TO SELF --- Romney steered hard right through the primaries and pre-primaries)
Third, The RNC looks for some silver lining (you know, Obama is a lame duck)
Fourth, the think tanks will begin the process of introspection.
In 1989, I worked on Capitol Hill and we held a series of brown bag lunches to discuss how we had had our asses kicked for the third time in a row and the Democrats had won only 1 of 6 elections for the White House since 1968.
I don't remember who, but a congressional staffer offered us some interesting thoughts.
