GW is a moron.
obviously for tactical reasons....try to take out Cruz...he’s in single digits as well and hope that you can add some of his voters to your side and see if you can’t get above 10%. Attacking the front runner has been a loser for !Yeb so it’s time to knock out someone he thinks he can take.
Now, whether they actually can take down Cruz is another matter. I don’t think they can...and I would be willing to bet dollars to donuts that Trump will jump into the fray and diffuse the situation and take some of the heat off Cruz.
