As more and more comes out and the regime continues to try to withhold informations, fight subpoenas (there's some tough guys on that committee that won't drop this), it could affect the midterms. Keep in mind, the dems are politicizing this, not the republicans. It's pretty obvious, even to the low information idiots. They keep up with their attitudes, poo pooing the deaths of these men, it might even affect a few senate races. When McCain & Graham are against them, you know they have a problem.
I think thos witnesses were 0bamas "blue dress" moment. Regardless of how har the left tried, they couldn't make these men look bad, vindictive or partisan, tho they managed to make themselves look that way.
If the house keeps pushing in spite of the obvious criticism they'll get, this could be a train wreck for the boy king and his thugs. And Issa doesn't give a rat's ass what they say about him.
