Be weary of those Senators that try to vote against Cloture not because they stand with Cruz, but to save their hide if it becomes apparent that their vote isn’t needed to give Harry Reid what he wants, allowing them political cover.(i.e. Jeff Flake, if this information is correct)

this is what I think this is about. Notice the author says this will most likely fail.

If enough dems vote this way expect the hold out Rs to delay their votes till the very last. Chicken Senate style!
