I agree with you for the first 2/3 of that post. Obviously, you are free to vote for leftist that oppose freedom, biology, religious freedom, life and want to tax you into oblivion to make the point that you hate Trump. Everything that you hate about Trump, the left has just as much, if not more. Do you think the left cares about kids separated from parents at the border? Of course they don't. If they did, they would be supporting Cruz's bill, which is specific bill to solve this issue, not soiled by tying other things into it. They are every bit as immoral. Every bit as vile. Every bit as narcissistic and every bit as evil as Trump is. I simply don't understand the concept of supporting all of that just to get back at a man that isn't on the ballot. The Democrats cannot remove him from office, as that takes 67 votes in the Senate. At best, you are going to stall the limited good stuff we get through policy. You may simply get Trump to start signing on to leftist policies to get a "win".
I even understand if you said no Republicans and voted third party. I don't understand cutting your nose off to spite your face. Voting Democrat because of the legitimate issues with the GOP is like firing a guy for smoking weed and hiring a new one that smokes crack. You are going backwards.
On an individual level, Cruz is actually one of the only people in Washington trying to solve this problem. Everyone else is using it to score political points. Is he going to get on CNN and bash Trump? No, he isn't. Cruz wants to be President one day and doing that gets you the Mark Sanford treatment. You can criticize that if you want, but I would like to have some serious options for President in the next two decades that I can actively support.
Besides the logical problems with it, did any single person do more and work harder to prevent Trump than Ted Cruz? I don't think so. The man put everything he had into stopping Trump (by winning himself) and came pretty close to making it happen if he had a few earlier events break his way (such as Rubio dropping out after getting shellacked). I am not really sure what you want from the guy. If Cruz came out and condemned Trump for all of his many antics (which I assume is what you want), he would be Mr. Cruz, probably defeated in the primary. What good does that do? Then we have an establishment toadie that will take his place in the Senate, give verbal fealty to Trump and spend the next 6 years working against conservatives. Cruz doesn't defend the antics, he just refuses to talk about anything other than policy. I think it is the perfect strategy. It keeps him viable politically and keeps him from having to defend the indefensible.
I understand your frustration. I just think your solution doesn't solve the problem, it actually makes it worse. Trump's only control is pressure from the right. Without that, he most likely gets worse.
