Ted Cruz stumped for Pat Roberts, as did Sarah Palin and for good reason. They understand the need to start with a democrat defeat in the Senate, they're clearly not part of the purity assinity of FR.
You need to think more clearly ahead, when (hopefully) Cruz wins the nomination, and then the presidency, he will need all the help in the Senate he can get in order to govern, and that ain't coming from the rats. I'm surprised you don't understand that Cruz won't govern like the dictator we have now, and he will need a GOP congress, as heavily weighted as possible.
Kindly think a little deeper on this.
Question: How would allowing GOP wins change things? This is to ask, what in recent history shows that the GOP having more power, in any shape or form, would be rightly used?
Or, to draw on a common christian parable:
(Matthew 25:14-30)The Republican party, as a party, has proven themselves to be wicked and slothful servants, squandering that which was given them — why do you wish to reward them?
“For it will be like a man going on a journey, who called his servants and entrusted to them his property. To one he gave five talents, to another two, to another one, to each according to his ability. Then he went away.
He who had received the five talents went at once and traded with them, and he made five talents more. So also he who had the two talents made two talents more. But he who had received the one talent went and dug in the ground and hid his master's money.
Now after a long time the master of those servants came and settled accounts with them. And he who had received the five talents came forward, bringing five talents more, saying, ‘Master, you delivered to me five talents; here I have made five talents more.’
His master said to him, ‘Well done, good and faithful servant. You have been faithful over a little; I will set you over much. Enter into the joy of your master.’
And he also who had the two talents came forward, saying, ‘Master, you delivered to me two talents; here I have made two talents more.’
His master said to him, ‘Well done, good and faithful servant. You have been faithful over a little; I will set you over much. Enter into the joy of your master.’
He also who had received the one talent came forward, saying, ‘Master, I knew you to be a hard man, reaping where you did not sow, and gathering where you scattered no seed, so I was afraid, and I went and hid your talent in the ground. Here you have what is yours.’
But his master answered him, ‘You wicked and slothful servant! You knew that I reap where I have not sown and gather where I scattered no seed? Then you ought to have invested my money with the bankers, and at my coming I should have received what was my own with interest. So take the talent from him and give it to him who has the ten talents. For to everyone who has will more be given, and he will have an abundance. But from the one who has not, even what he has will be taken away. And cast the worthless servant into the outer darkness. In that place there will be weeping and gnashing of teeth.’
