About an hour into the Republican National Convention on Wednesday night, convention officials presented a video tribute to Rep. Ron Paul (R) of Texas, whose grass-roots efforts during the Republican primary attracted an energetic and loyal following.

The question now is whether those same loyal Paul supporters will become loyal Romney supporters, or at least Romney voters by November.
