Marco Rubio Is Running for Re-Election 'I've changed my mind' By Arden Dier, Newser Staff Posted Jun 22, 2016 10:25 AM CDT 56 comments Comments It's official. (AP Photo/Alan Diaz, File) (Newser) – "I have only said like 10000 times I will be a private citizen in January," Marco Rubio tweeted last month. There's a very good chance that may not be the case. After much debate, the failed presidential candidate says he will seek re-election in the Senate, which the Washington Post sees as bolstering the GOP's chances of keeping its majority and makes this competitive race the one to watch. Rubio announced his decision Wednesday to the Miami Herald, noting "control of the Senate could very well come down to what happens in the Florida race." Rubio recently revealed the Orlando shooting and support of his friend running for the seat made him rethink his earlier decision not to run. He had until this Friday to make up his mind. "No matter who's elected president, there's reason to worry," he continued, saying Hillary Clinton would continue failed economic and foreign policies and that Donald Trump is "worrisome." Senate Majority Leader Mitch McConnell says Rubio's change of heart is "a great outcome." A Quinnipiac University poll released Wednesday has Rubio seven points ahead of Democrat challenger Patrick Murphy and eight points ahead of Democrat Alan Grayson, reports the South Florida Sun-Sentinel. The four other Republican candidates trail behind both Murphy and Grayson. Republican Carlos Lopez-Cantera (the aforementioned friend) dropped out and Rep. Ron DeSantis may do the same with Rubio's decision, leaving Rubio, Carlos Beruff, and Todd Wilcox on the Republican side, per the Herald.
