It's not totally unusual for a sitting president to hold campaign rallies, but Trump has already held
24 rallies since the 2016 election. President Obama had his first post-inaugural rally nearly six months into his presidency, which specifically focused on garnering support for a fellow Democrat's re-election campaign. President Trump's rallies, on the other hand, do not appear to be designed to support other candidates or push specific policy objectives.
Trump’s tactics aren’t new, but his agenda is. His emotional campaigning serves solely as a tool for self-aggrandizement, rather than fulfilling its historic function of channeling voter enthusiasm toward a particular legislative program. His rallies, which are notably about him and not about policies, raise deep concerns about a president who uses emotional politics to build a cult of personality rather than to pass laws.
