It is surprising to me that so many posters here don't see why the Rats achieve their goals and the Pubs come up short.
The Rats will exercise tough party discipline on key issues. If they need the votes everybody better vote for whatever it is they want, or their career in and out of office is done. They get tax increases through, they fund abortion, they grow govt.
The Pubs can't stop them even when they are the majority because the pubs play "nice" while the Rats are fighting for life or death.
The Pub party has no discipline. There are no consequences for breaking key campaign promises. Pres. Trump is right and people don't like it that he's naming names and placing blame. I just wish he would take the next step and stop endorsing establishment candidates.
