Trump didn't require an actual investigation. He just wanted it announced by the president of Ukraine to hurt Biden's standing. There is zero evidence that Joe Biden did anything criminal, and plenty of evidence that Trump did.
And state department officials testified that Trump put national security at risk by compromising the defenses of a friendly nation in a hot war with an unfriendly nation in defiance of Congress providing military aid to Ukraine. The blow job did nothing to compromise security.
But I guess you can't expect the radical right to see the difference since they are so blinded by partisan politics.
