Not necessarily. The Whig party “stood,” but was replaced. The Federalists stood, but were replaced. The Democratic Republicans were replaced.
I understand, different times in terms of money, but what a man can conceive can be done.
Modern American political parties depend on mass support, and when a party's elected officials disappoint its supporters, the efficient and reliable remedy is to replace those elected officials in primaries or await or work for their defeat in the general election.
Otherwise, creating a new political party to displace an existing one requires developing mass support, an expensive and time-consuming task akin to establishing a new mass retailer to compete with WalMart and Target. Not likely.
Moreover, as with retailers facing a new rival, the party targeted can adjust their issues and performance to prevent support for the new party from solidifying and getting large enough to be a danger. For example, even with major funding and as the big libertarian issue of marijuana legalization is gaining victories, the Libertarian Party itself remains a marginal influence as a political party.
As for the health care issue, I am confident that GOP members of Congress will get pummelled by their constituents during the summer and holiday recesses. They will return with stiffened spines and renewed worry over the prospects for keeping their majorities.
