A politician inherently dedicates their standing in government to a particular party and support those who support similar views. They have each others backs in large scale politics, as members of both parties look to attack and gain ground on one another.
In the case of Donald Trump, representatives of the Republican Party, many of which road their success on the backing of Trump, sold him out in an instant over impeachment voting.
These Republicans who voted against Trump, did so with the intention of bettering their own positions and political goals. What they did not see was Trump’s perseverance to avenge what attacks and lack of support these people had for him.
All of these Republicans now face primary challengers, backed by the support of Donald Trump.
