Last year, Trump reportedly spent $1 million on political research in consideration of a presidential bid, and since 2013 he’s made several trips to Iowa to meet with social conservatives. Trump spent months teasing his potential candidacy in 2012 before deciding not to run. Many observers don’t take his presidential musings seriously, saying he’s more concerned with generating headlines and enhancing his global business brand. Still, the media attention he’d get during a potential run would shake-up the political scene, and Trump has supporters. In early 2011, some polls showed Trump leading the entire field of GOP candidates. He said he wouldn't run before any debates, caucuses or primaries.
