Senior U.S. Sen. John McCain may not have decided whether to seek re-election in 2016, but he is making all the moves to ensure that he can mount an intimidating campaign if he decides to seek a sixth term.

McCain, R-Ariz., is set to headline an April 24 re-election fundraiser at the Ritz-Carlton, Phoenix, at 24th Street and Camelback Road in Phoenix, according to an invitation for the event obtained by The Arizona Republic. And he is putting together a network of political support.

Asked about the event Friday, McCain told The Republic that while he still has not made a final decision to seek a sixth Senate term, he has never taken a race for granted and wants “to make sure that we are fully prepared when I make a decision, if I decide to run again.” He previously has held re-election fundraisers in New York City, Denver, Las Vegas and Washington, D.C., but April 24 will be his first in Arizona.
