When Joe Lieberman was running for Vice President, he also ran for reelection to his Connecticut Senate seat, a move that generated some controversy. I vaguely recall that he was permitted to do so through a quirk of Connecticut law, but that running simultaneously for Vice President and Congress would be barred in some other states. In the end, Lieberman lost the Vice Presidency and retained his Senate seat.
Since Mitt Romney has now picked Paul Ryan as his running mate, will he have to drop out of the election for his Wisconsin House seat, or can he still run to retain his House seat while seeking the Vice Presidency?
(If it is possible, any discussion of the wisdom of doing so would likely be better suited to the Elections forum.)
