PHOENIX (AP) — Ron Barber's decisive victory in a special election for the congressional seat held by his old boss and fellow mass shooting survivor Gabrielle Giffords is raising questions over whether his Republican opponent will continue to campaign for the November election.
Tea party Republican Jesse Kelly lost Tuesday's election by 6 percentage points.
Analysts say that's a significant margin considering that the district voted for Republicans the last two presidential elections and that Kelly very nearly unseated Giffords in the 2010 campaign.
Barber, who is expected to be sworn into Congress on Tuesday, will have to win over voters again in the Aug. 28 primary and Nov. 6 general election.
Kelly says he's "reflecting on the future" and would have an announcement about his plans by the end of the week.
