The Hurdles Along Michael Bloomberg's Path If He Runs for President

Money certainly helps, but a ground game is critical.

Indeed, he would face more obstacles by not running in one of the established political parties.

The Logistics of Breaking Out on Your Own

One of the most immediate challenges for a serious independent candidate would be to make sure his or her name showed up on the ballots in all 50 states, Georgetown University associate professor Hans Noel told ABC News.

The states differ dramatically on the requirements to qualify to have a candidate’s name added to a ballot. Generally, states require a certain percentage of the electorate to sign a petition to have the individual added to the ballot, ranging from more than 178,000 people in California to as few as 275 people in Tennessee, according to Ballotpedia, a website run by a nonprofit focused on government accountability.

The individual filing deadlines range mostly through the summer months, with Texas having the earliest deadline of May 9, according to the site.

A candidate would likely want to hire someone in each state with local expertise, but, Noel points out, most of those individuals have that experience because they’ve been working for one of the main parties "for decades," making them less likely to break away for an independent.

Beyond that, the candidate in question would need to solicit thousands of signatures, indicating widespread appeal.

"If the barrier to an independent candidate were that they couldn’t mobilize enough people to get on the ballot in the 50 states, then that's somebody that’s not going to win," Noel said.

Past Cases

Noel explained that, essentially, Wilson held on to the majority of the Democrats, Roosevelt and Taft effectively split the Republicans, costing themselves the election.

"It’s reasonable to suggest that either had Roosevelt not run or Taft not run, either one of them might have beat Wilson, but because they were both in the race, neither won," Noel said.

"Whichever party he is closest to, his running helps the other candidate," Noel said.

Beyond ballot access and political posturing, the biggest factor that will prove difficult is that Bloomberg would have to win – not come in second, but win – a sizeable number of states to seriously compete with the Democratic and Republican nominees.

"You could end up coming in second behind the Democrat in a lot Democratic states and end up coming in second behind the Republican in a lot Republican states and win no electoral college states at all," Noel said.

In the case of Perot in 1992, he earned 18.9 percent of the vote but those votes were from "all over the place," so he didn’t collect any electoral college votes.

"Swing states might be the place [Bloomberg] would be more likely to win because these are places that both of the other two parties are evenly matched, so he might be able to squeeze in there," Noel said. "Those places are larger and more diverse."
