The reality is that you want to forge something you start with some appropriate raw material. You want to make a sword, you need the right material. Most of the Congress is just wet crap.
You are not going to get wholesale turnover in Congress. I wish we had 51 Ted Cruzes in the Senate, but that is not going to happen. So either you figure out a way to lead/inspire other members, or you sit smug and self-satisfied as a coalition of one in a chamber of a hundred.
Go ahead and blame Cruz if you want to, it's like blaming the one-eyed man in the land of the blind because none of the rest believe the elephant he sees exists.
The one-eyed man can either attempt to lead the blind, or mock them. I think Cruz has chosen the latter route.
Our whole civilization has bases on the acts of single men, be that Moses, Jesus, Galileo, Columbus, Billy Mitchell, or a host of others who didn't 'go along to get along', they were simply right. And none of them were politicians in a democratic system, where you need majority support to accomplish anything. Cruz martyring himself won't get him or anyone else elected to higher office. The one with the guts to stand up and say, "The emperor is naked!" seldom gets either accolades nor credit. When you are right you stick to your guns and let those who are wrong show their mettle.
None of the people you mentioned were politicians working within a democratic system. That is the profession Cruz has chosen, and that requires votes to be successful. Your "man standing alone" image sounds wonderful, but it is not how democracy works. Being right, but lacking the ability to persuade others to your point of view, is of little value to a political leader. It would be different if we were living in an overwhelmingly conservative country that elected conservatives, because persuading people to conservatism wouldn't be necessary. But we aren't, and it is.
Whether or not you have any admiration for that, whether that incites you to send people to Washington who will work with him instead of sit on the sidelines going 'tut-tut" and blaming Cruz speaks volumes about you.
I admire the principles for which he stands, and I've voted for like-minded people. But that is not enough, because the people who think as we do are not the majority.
Cruz is right on most of the issues, but his political skills are insufficient. Given that he has chosen a career as a
politician, his lack of ability to appeal to those who don't already share his views is a major drawback. But if you don't care if the guy you support is able to persuade others, and him simply being "right" is enough even if it means losing elections, then that speaks volumes about
you. You'd prefer a martyr rather than actually fixing the country.
Immigration is hardly the only issue the GOP has ignored the voters on....
I think it was the primary one that enabled the Trump movement. Trump doesn't say squat about fiscal discipline, and got 40% of the votes anyway. It was immigration, coupled with his defiance of political correctness, that was the vehicle he road to the nomination. If you disagree, fine.
