The weirdest example was Joe Miller running on "its horrible that the Alaska government gave the Governor's daughter a U.S. Senate seat, but things would be soooooo much better if they'd just repeal the 17th so she could have that seat for life without pesky elections in the way!"
That, and Rick Perry running a schizo platform of "its horrible that we amended the constitution so voters can choose the legislative branch instead of having politicians appoint them, but things would be AWESOME if we amended the constitution so voters can choose the JUDICIAL branch instead of having politicians appoint them!
Voters have little interest in choosing judges. A small minority of voters could easily elect radical judges and completely shred the Constitution.
