As Bloomberg weighs White House run, Iowa voters ask, 'Who?'

DAVENPORT, Iowa (AP) — Former New York Mayor Michael Bloomberg's latest flirtation with a White House run has set the political world aflutter.

But in Iowa, some people are wondering, who?

Bloomberg's standing with politically savvy Iowans underscores one of his biggest challenges if he were to make a late entrance into the race.

The prospect of Bloomberg launching a third-party presidential campaign has been speculated about for years. But he's largely unknown to many Americans and would be entering the race well after his rivals started introducing themselves to potential voters.  AP
