With regards to your question, get back to me in four years and we`ll talk. In the mean time, you have no idea what Trump`s thinking or planning with regards to Ryan. Trump keeps his plans close to his vest - not his ultimate goals- but his strategy for achieving them. That`s why he was and is the only Republican capable of moving the conservative agenda forward. And that includes repeal of Obamacare.
Grandstanding is not a strategy. Ask yourself what Ted Cruz, or whatever conservative hero of the month you wish to chose, would have done differently in dealing with the same Congress - the same Paul Ryan, the same obstructionist Dems, and the same Freedom Caucusas Trump is dealing with. And honestly ask yourself whether they would have been able to achieve the ends you desire, and how they would have done so. Patience grasshopper. Trump is the only one who has a clue how to navigate this minefield of squabbling, preening egos known as Congress.
Obamacare will end - just not as quickly as you would like. But unlike with a president Cruz or Walker, it will end.
capable of implementing his agenda
Trump is incapable of strategic or even tactical thinking. He has to hire it done. He also telegraphs every move he makes. You can see his tells a mile away.
When you talk of a squabbling, preening ego you are talking about Trump. Walker has accomplished a great deal as Governor of Wisconsin and Cruz did as well as the Texas Attorney General. You conveniently forget that.
