You won't get any arguments on that point. Except from the OK Republican and the OK Democratic Party!
Of course not. Nobody wants to make it easier for someone else to take their job. Like I have been saying for years, the trick is for all of those who support other parties to get busy and collect enough signatures to get their party on the ballot. Start at the local elections and build a base to get the rules changed. Until then all it is, is whining.
