Rush Limbaugh said it the best, and I will paraphrase:
'When the "good" compromises with the "evil," the "good" always loses.'
Assuming that we don't have a conservative candidate win the primaries, which I sincerely hope happens, we have the following with which to contend:
It is also a compromise with evil not to vote or to cast a futile vote.
Constitution doesn't have a chance. Libertarian doesn't either, but they're as liberal as they are conservative. 3rd party run....it'll split the vote and guarantee failure. (Lived through that with Perot.)
Therefore, you are left with the choice:
a) Hillary
b) Liberal to Moderate Liberal Fiscal Conservative Republican. (and if the conservative candidate gets enough votes, he'll be the VP candidate.)
Which is the best choice?
Yup. There is no compromise in the matter of life or death. You are either living or dead! Abortion is death. Abortion is the murder of an innocent and helpless unborn human baby. Murder is evil. Abortion is evil. There is no compromise possible.
