But if you do not like any or the republicans nominated during your lifetime maybe the problem is your simply not a republican. There has been a push from the far right over party to sell they idea that they are the only true conservatives and to attack anyone who does meet their purity test. They rant and rage when the center of the party compromises and willing to flip over the board and go home if they can't get their way. The problem is they live in democracy and they are not majority. They have enough numbers and passion to influence primaries but they kill the party when it comes to general elections because they manage to nominate an unelectable extremist or they stay home because the unelectable extremist they supported lost. They are the true RINOs.
The reality is the best you can hope for in a two party system is to try and pick the best person who can win knowing that you won't get everything you want but hoping your vote will move things slightly in the direction you want. That is how democracy works.
The real problem with Trump isn't his politics, outside of a few wedge issues that he would never get through congress he doesn't have any. The real problems is he is populist entertainer playing on the emotions of people whose sense of entitlement has let them to point where they feel cheated because their unreasonable demands have not been met. Any many way Trump supporters remind me of the Black Lives Matter group where fact and reality must give way to emotion and t the TRUTH.
