Well, yes he was grasping at straws
So, one fringe Republican makes an outrageous statement. R.L's statement made it sound like this was the common viewpoint of "some senators we have just elected" (note the plural). This is an attempt to tar a group with the statements of an individual.
Perhaps I'm mistaken, but weren't you complaining to Tom</a. about him doing the same thing to Democrats just yesterday? You wrote, One Bowser does not the Democratic Party maketh. True, and one Tom Coburn does not the Republican Party maketh, either.
