The only time I can remember an effective speech by a member of the opposing party is when DEM Zell Miller spoke in favor of Bush at the RNC 2004 convention.
No one can ever forget his Kerry Spitballs!!!!!
That was SMOKIN’ great!
The reason Miller was so effective was that he was driven from the Democrat party because of their harmful policies. The Never Trumpers are just having temper tantrums, and are pretending that they're still conservatives.
