Newly-installed Fannie Mae CEO Herb Allison, Jr. was national finance chair of John McCain's Republican presidential bid in 2000 and as recently as 2006 he wrote a $5,000 check to McCain's Straight Talk America PAC. But a year later Allison switched his party affiliation to Democrat and this year he's contributed $4,600, the maximum allowed by law, to Barack Obama.
Allison, 65, voted as a registered Republican in New York in the November 2006 election, but a year later registered as a Democrat in Connecticut and voted as one in that state's primary on Super Tuesday, February 5, 2008.
Allison sent a pair of $2,300 checks to the Obama campaign, the most recent on August 25, two weeks before the government seized the struggling mortgage guarantor and put him in charge of it. Previously, Allison's political giving favored Republicans, but he's also donated to New York Sen. Charles Schumer and a few other Democrats.
He hasn't given anything to McCain since 2006, according to the non-partisan Opensecrets.org campaign finance web site.
