If you are a conservative, may it be suggested that you DO NOT work to be accepted by the Republican party, but rather work to take over the Republican party. And... if you happen to be a third-party advocate, may it be suggested that you also direct your efforts toward taking over the Republican party, because within the party you will find many who are just as angry with the "old guard" GOP as you are.
So, how can you have influence in this "take over" process? Again, a suggestion: E-mail, write, call your local & state GOP Committees and let them know that you WILL NOT vote for any GOP-endorsed candidate unless he/she has solid Conservative credentials, or is a candidate who has emerged from the Tea Party movement. Important: encourage your like-minded friends to do the same.
And please don't forget that old standby: write Letters to the Editor.
Finally, an opinion: Scott Brown's strong showing in Massachusetts is not because of the Republican party, but because Scott Brown is a Conservative and proud of it. There's a lesson to be learned here.
Together, we can make all this happen.
