Mike Bloomberg exaggerates his support for Obama in 2008, 2012

The fact that Mike Bloomberg hasn’t been a Democrat his whole life keeps coming up in his 2020 presidential bid.

At a CNN town hall, host Anderson Cooper asked Bloomberg why Democrats should trust him to lead their party. Bloomberg acknowledged his past as a Republican and an Independent. But he argued that he isn’t such a Democratic outsider if you look at who he supported.

"But if you want to know my Democratic credentials, I spoke for Hillary Clinton at the DNC Convention in Philadelphia in 2016," Bloomberg said at the Feb. 26 forum. "I certainly supported Barack Obama and Joe Biden, (Biden) says no, but I was there both times for them, thank you very much."

Was Bloomberg really there for Obama and Biden in their 2008 and 2012 campaigns for the White House?

It would be a stretch to say he was an enthusiastic Obama supporter. Bloomberg did not endorse Obama’s 2008 run, and while he did endorse him in 2012, that happened a week before the November election in an opinion piece that also criticized Obama’s record.

"Mike said he supported Obama both times. He voted for him both times," said Stu Loeser, a Bloomberg campaign spokesman.

Obama’s 2008 bid was plagued with rumors that he was secretly a Muslim with anti-Israel views. Bloomberg, who is Jewish, flew to Florida in June 2008 to defend Obama. Bloomberg at that time was mayor of New York City.

The rumors about Obama were lies, Bloomberg told the Jewish Federation of South Palm Beach County, "wedge politics at its worst, and we have to reject it — loudly, clearly and unequivocally."

Bloomberg told the audience he had not decided whom to support, the New York Times reported. When he was asked whether he would become an ambassador to Jews for Obama, Bloomberg said he would "speak out against intolerance for both candidates," including Republican nominee Sen. John McCain.

In a July 2008 speech to the Independence Party of Minnesota, Bloomberg spoke about both Obama and McCain, without picking a side. "Now, we're lucky this year: we have two candidates who have shown, on at least some issues, that they are capable of thinking and acting independently of the special interests," Bloomberg said.

Overall, Bloomberg delivered a largely neutral stance in 2008. He did not endorse either of the party candidates.

Bloomberg endorsed Obama Nov. 1, 2012, in a Bloomberg.com post headlined, "A vote for a president to lead on climate change."

If African-Americans vote their percentage of the population in 2008, "Mississippi is suddenly a Democratic state."

Bloomberg lauded Obama’s efforts to reduce carbon consumption, for setting higher fuel-efficiency standards for cars and trucks, and for adopting tighter controls on mercury emissions.

But he also said Obama had not done enough to build a coalition of centrists, "which doomed hope for any real progress on illegal guns, immigration, tax reform, job creation and deficit reduction."

"And rather than uniting the country around a message of shared sacrifice, he engaged in partisan attacks and has embraced a divisive populist agenda focused more on redistributing income than creating it," Bloomberg wrote in his endorsement.

Loeser told PolitiFact that Bloomberg’s endorsement was "designed to flip or lock down voters who still hadn't committed to Obama-Biden by the last days of the campaign."

Bloomberg said, "I certainly supported Barack Obama and Joe Biden. ... I was there both times for them."

In 2008, Bloomberg defended Obama against attacks that he was anti-Israel, but Bloomberg did not endorse a presidential candidate that cycle.

In 2012, he endorsed Obama’s re-election in a post that mixed in criticism of his record.
