Long, a former auctioneer, was elected in the 2010 tea-party wave to the seat formerly held by Sen. Roy Blunt (R-Mo.), who also serves as the Romney campaign’s liaison on Capitol Hill.

In addition to Long, the other Missouri legislators backing Romney are six state senators and representatives including state Senate President Pro Tem Rob Mayer and two county committeemen.
