Unlike the previous administration, Trump moved very fast in his first week in office. These are major policies. It is important these policies are aligned with his campaign promises. Based on the current polls, his voters are very satisfied, and the polls are not meaningless at all. This is not the Biden administration which not much was done in the first week.
Trump has been at the center stage of American politics since 2016. Normally when you are there you lose political capital over time. The fact that Trump’s approval and favorability rating is at the highest after 8 years is ridiculously amazing.
