Conservative Republicans have been saying that for years, and it hasn't happened yet.
Liberals are coddled and financed. Conservative candidates are savagely attacked and undermined, and defunded.
Just happened again this past week in a congressional special election in California. A solid conservative candidate was within striking distance and couldn't get the Republican Party to cut loose one thin dime.
At some point you have to listen to Einstein:
"Insanity: doing the same thing over and over again and expecting different results."
You get it started, its gets off to a good start, lots of money good people and then they have to deal with the political hacks in dc to get anything done.
Sooner or later we get those who decide if we just go along to get along we can get further and get more done.
It's very possible the same things that have destroyed the Republican party could rear their ugly heads again in a new party. Certain areas of the country are just too prone to it,Maine,the north east, both coasts etc. IMHO, the best way is to clean up the Republican Party, it may take a while, and make it a political party one can be proud of. We know the drill, it won't be easy but it is doable.
