Joe Lieberman ran for senate re-election at the same time he was running for VP with Gore.
I once had respect for the guy, but not after that move.
Probably thought to himself, "This Gore guy seems to be a little off kilter and will probably find a way to blow it. Think I'll run at the same time for my nice safe senate seat. The voters in this state are clueless and won't even notice the disrespect I'm showing them.

Have to do what's best for your constituency. Right?
In 1960 Lyndon Johnson also ran for vice president and ran for re-election to the senate at the same time. He probably thought much the same as you speculate Lieberman thought: that there was a fair chance his ticket would not win the White House, and therefore it would be foolish to let go of the senate seat.
The difference between Lieberman and Johnson is that Johnson
won both elections. In retrospect, then, the case can be made that what Johnson did was selfish, and inconsiderate to his constituents, putting his own interests ahead of theirs.
Lieberman, in contrast, won re-election to the senate but did not win the vice presidency. He was criticized during the election campaign for not standing aside on his senate run so that some other Democrat could have a shot at it, but in retrospect it turned out that the decision he made actually served the interests of his supporters better than if he had bowed out of the senate race.
Because he stayed in the race, his senate seat continued to be held by a Democrat (and a Democrat with considerable influence and seniority). So, arguably, he made the right choice and was actually showing
respect for the voters who had put him in office.
(Of course, by refusing to give up the senate race, he displayed an apparent lack of confidence in the Gore-Lieberman ticket which may have led some voters to lack confidence in it as well, and thus may have contributed in some small way to the defeat. So one could argue he showed a lack of respect for Gore by continuing his senate run even after being picked for the VP slot. But the case that he was disrespecting the voters is a little shakier, until we perfect our mind-reading techniques and are able to read exactly what thinking went into his decision.)
