But I thought the Trump campaign was a joke and out of money according to the media."..... Donald Trump comes out of his convention ahead of Hillary Clinton in the race for the White House, topping her 44% to 39% in a four-way matchup including Gary Johnson (9%) and Jill Stein (3%) and by three points in a two-way head-to-head, 48% to 45%. That latter finding represents a 6-point convention bounce for Trump, which are traditionally measured in two-way matchups."

Some recent history on post-convention bumps --
in 2008 McCain had a small one
In 2004 Romney lost 1% (bascially Romney & Obama were tied in the low 40s, then BHO slowly gained steady ground)
In 2000, Gore gained 10% on Bush
