It's why she will probably never be able to be President. They see her as a threat just like they did Clinton. They spent 20 years demonizing Hilary Clinton prior to her running for President, and because the Dems ran her anyway we got Trump. They've been doing the same thing with AOC.

Obama was able to become President because he was an amazing orator who the country had never paid attention to, and the GOP wasn't prepared. John McCain was the best Candidate the GOP ever ran, and he didn't have a chance against Obama because the GOP didn't have a playbook for dealing with a strong, unknown candidate who could speak coherently.
