These people will just help the liberal Democrats by splitting the conservative vote.

None of the names mentioned above could get enough votes to make an impact. The GOP candidate only has to fear a charismatic conservative or populist running as an Independent.

I think the presidential election in 2000 was determined by a few hundred votes in Florida. Conservatives have lost some Senate seats in recent years because of right wing splinter parties. (Libertarians) Of course it would be great if the American electorate was conservative enough that we could afford to split our vote but that is not the case.
