Jeb Bush promoting middle class policies in Detroit, 2016 prospect plans March trip to Iowa

Former Florida Gov. Jeb Bush is to deliver what aides call an "optimistic, conservative vision for the future" in his first unpaid speech since declaring his interest in a bid for the Republican presidential nomination in 2016.

The son and brother of former presidents George H.W. Bush and George W. Bush is scheduled to speak at the Detroit Economic Club and offer what is expected to be the theme of a national campaign. He's to attend a fundraiser in Detroit Wednesday evening.

Bush's speech, aides said, is aimed at underscoring his desire to reinvigorate the middle class, which he argues has languished despite the ongoing economic recovery. Conservative economic policies, he says, would provide incentive for middle-income families to reach higher income potential.

The speech represents a departure for Bush, who until Wednesday, has spoken only at paid events and private fundraisers. The event is also a first in a series of stops his calls his "Right to Rise" tour, borrowing from his economic mantra and the name of the political action committee he formed in December.

Aides also confirmed that Bush plans to make his first trip to Iowa as a presidential prospect in March. Bush plans to participate in an agricultural policy forum hosted by Republican Gov. Terry Branstad and agribusiness leader Bruce Rastetter.
