MEMPHIS, Tenn. - (AP) - The Tennessee Democratic Party voted to remove a state representative from the party's primary ballot over allegations that he had Republican donor financing and voted contrary to the party.

SECTION 4. PRIMARY ELECTION NEUTRALITY:
(a) The Tennessee Democratic Executive Committee shall not endorse or campaign for any specific Democratic Party primary candidate prior to or during a contested local, state, or national Democratic Party Primary Election.
I'd love to hear from someone with a serious understanding of Tennessee primary elections. Since when did ANY state committee get to disqualify candidates in a primary election simply because the executive committee (in other places, like Stalinist Russia or China today, the Central Committee) dislikes said candidate's politics? This guy may have a straightforward legal case against the State Committee. If he presses such a case and wins, Republicans should note that Tennessee has an open primary.
