I'm not buying it. They could have made an issue out of it all along and still used at election time, probably even more effectively since the great unwashed who pay no attention to politics untill two weeks before an election (and greatly outnumber us political junkies of either party) won't have a clue what they are talking about if they do bring it up next year.
The 'RATs have given the GOP plenty of ammo over the years, including unabashed treason, and the GOP never uses any of it.
When is the last time one of them uttered a word about selling misiles to China? When is the last time one of them anything about illegal Chinese money contributions? How come none of them are saying squat about how North Korea got the nukes it is pointing at the neighbors and marketing to terrorist nations right now?
And if the strategy story were true, what does it say about the character of a party that would string a man along for two years of his life on a bogus job offer just to generate a political prop?
