Who is that "us", and what percent of voters are they?
Starting a third party doesn't solve the real problem, which is a lack of conservative consensus among voters.
Well, for instance, if you can get the Christian Right to vote en bloc, they are the biggest natural voting bloc there is.
There are more Conservatives outside of the Republican party than in it, and that has been true for a long time.
There may be some movement between the parties, and a lot of movement in independents... But the money shot are the disaffected. Especially with Conservatives - They tend to be working class, and entrepreneurs... Getting them to drop everything and take the time to vote is the trick.
The same with Christians. Their focus is on the eternal, not the political. Getting them to vote en masse means you have to walk the walk.. and you have to fight their fight.
The same with Foreign Policy wonks and surely veterans and DEFCons... How many vets are going to turn out for a man that has taken their oath and has been in battle, and earned medals... The answer is ALL of them.
Right now, in all of those factions, many don't turn out, because just like me, they don't want what Republicans are selling, or don't believe they are really going to fight.
And who said anything about another party?
If the Republicans would vote their conscience and hold fast to the principles that bind us, the party could be reformed... As I said, TEA Party style.
Draw the line, hold the line, and don't settle for less. Believe it or not, THAT is Reagan.
