Vote across party lines all you want. But hijacking a parties primary process is anything but ethical.
You: Voting in an election? Why, that's unconstituionamable!Won't someone think of the constimatution?!?!
Wet lunch? Where is anything in the first quote unconstitutional? How does wanting to hold party unity become unconstitutional? Where does it say in the constitution that political parties must allow non-party members to switch their affiliation for the sole purpose of influencing that party's vote? Where?
Nowhere, and that's not the point. The point under discussion is PlainOleAmerican's screaming claim that, "NO TRUE 'CONSTITUTIONALIST' WOULD EVER USE SUCH TACTICS TO MANIPULATE A REPRESENTATIVE REPUBLIC!". Regardless of what PlainOleAmerican seems to think, people voting for a candidate they like in accordance with laws passed by their elected representatives is not a nefarious undermining of the process. It is the process. The fact that they may be voting for a candidate you guys don't personally like doesn't change that.
