An unprecedented burst of spending by outside groups is heralding the start of President Trump's re-election campaign. "Independent expenditures for multiple hybrid-PACs advocating for Trump's candidacy totaled over $1.27 million since the start of this year," the Center for Responsive Politics reports, while at a similar point in President Obama's re-election campaign such spending totaled a few hundred thousand dollars.
And the three outside spending groups dominating this effort are all linked to Dan Backer, a prominent attorney advocating for a loosening of campaign finance rules: the Committee to Defend the President, the Great America PAC and America Fighting Back PAC.
