Do you believe that legal charges against political figures are more about law or politics, and why?

I believe that all politicians can be corrupt in different ways. For a politician to call out another politician for doing something unfavorable is hypocrisy. However, if evidence is provided that shows a blatant crime being committed, then said politician should be charged. But if there is not enough evidence to convict, even after extensive investigation, then charges should be dropped. If investigation still resumes, then the charges are more about politics than law.
