ABC News' Z. Byron Wolf reports; When Mitch McConnell endorsed the establishment Republican candidate in Kentucky, he released a paper statement singing Trey Grayson’s praises. But in the annals of political endorsements, McConnell’s goes into the tepid category: When he was given the opportunity to give Grayson a full-throated endorsement at a Capitol Hill press conference in front of TV cameras, McConnell couldn’t even find the man’s name. “The question relates to Kentucky politics,” McConnell said when asked by a reporter to elaborate on his endorsement. “I did today endorse one of the candidates, and I'll be there for whoever wins the primary and we'll find that out two weeks from today.” It is a crowded field in the Kentucky GOP primary this year and Grayson is behind in the polls to Rand Paul, son to Libertarian Republican and Rep. Ron Paul, R-Tex. Paul, who was seen as a long shot at the beginning of the race, has garnered support from the tea party movement and from outgoing Sen. Jim Bunning, R-Kentucky.
