The former New York City mayor is running for president on a centrist-friendly platform that’s mainly premised beating Donald Trump. What makes Bloomberg’s campaign stand out, however, is how much he’s spending to get his message out.

Bloomberg was spending more than $ 170,000 every day during the first week of December. On Google search terms related to climate change, $ 38.1 million on TV ads for this month alone.

buttigieg’s campaign, which is polling at 9 percent, has spent $ 4.6 million on Google ads since last April. His political action committee has also spent $ 9,796,400 in the same period of time.
