As the longtime Republican senator lays the groundwork for a likely 2016 reelection bid, his political team is engaging in an aggressive and systematic campaign to reshape the state GOP apparatus by ridding it of conservative firebrands and replacing them with steadfast allies…

The ambitious effort — detailed to POLITICO by nearly a dozen McCain operatives, donors, and friends — has stretched from office buildings in Alexandria, Virginia, where strategists plotted and fundraisers collected cash for a super PAC, to Vietnamese-American communities across Arizona, where recruiters sought out supporters eager to help the incumbent defeat the tea party.

If McCain had put in as much effort into running for president as he did in fighting conservatives, he would have been in the White House.

Until this year, however, McCain aides had never seriously considered a concerted effort to remake the state GOP apparatus, which has traditionally been dominated by his conservative antagonists. That changed after the January censure, which rapped the senator for having an insufficiently conservative record that was "harmful" to Arizona.
