The Republican party has lost its way since Watergate and 1974

5. I don't agree because Republicans have held the Senate, the House and the Presidency at times

They've been a majority party multiple times since their creation. Leaving out the Civil War era, they were a force again at the turn of the 20th century, during the 1920s, and the GW Bush eras. Even during the Reagan era when Democrats controlled the House, the GOP exerted tremendous influence and Reagan defeated Mondale in one of the biggest landslides.

That said, the GOP is a minority party now, and hopefully is on it's way to permanent minority status.
