Dictators
Donald Trump is a bully, plain and simple. He goes after anyone that opposes him or stands up to him. Republican politicians, much like their Democratic counterparts, put their political career above all else. An example of how scared our republican representatives in congress are, look back to the search for Kevin McCarthy's replacement, one nominee was opposed by Trump and his name was immediately withdrawn. Tim Scott, the US senator from my home state was absolutely shameless in his endorsement of Trump but did what he had to forward his political career. Nikki Haley is the only one willing to stand up to Trump, we should be grateful that she has the chutzpah to do so.
Attacking and silencing opponents and opposing views is the Method of Operation for Putin and Xi. Both are dictators serving beyond the term limits of their respective countries. Both have legislative bodies that do as they are told.
Since I originally wrote this post, Trump has said he doesn't like the new bipartisan compromise worked out for the border and Ukraine. Since the vast majority of representatives and senators either agree with Trump, are afraid of Trump, or both, the deal will die. Bare in mind, Trump doesn't hold any elected office but is calling the shots in congress.
Democrats are no better, the Democratic national party and the Republican national party are complacent in this and will not stand up to Biden or Trump.
Hopefully this helps you understand why I'm so concerned for our country and why we so desperately need Nikki Haley.
