Not to be argumentative, but there is no real, "Conservative Party" in America. The home of the conservative movement in America, is the Republican Party. If, one day, there was a true grassroots movement to create a viable "Conservative Party", I would consider joining it. Until and unless, that happens, I will remain in the Republican Party.
And as long as they can count on you to stick around, they'll continue to play you for a sucker.
Football teams exist to win football games, political parties exist to win elections. They'll say what it takes, do what it takes, to win elections. That's the long and short of it.
Sure there is. There's also a Liberal Party. They're both in Wew York, but that is part of America, after all. They're both obviously viable, since they've been around forever. And they do have elected officeholders, since NY election law allows a candidate to run as the candidate of more than one party; if the R or D is acceptable, he gets the nomination.
