Boehner, just like House Speaker Nancy Pelosi (D-Calif.), had said he would stay out of the presidential fray because of his role as chairman of his party’s convention. Blunt and Putnam also had not endorsed before Wednesday.
The three join a number of other Republicans to back McCain since last week, when former Massachusetts Gov. Mitt Romney, McCain’s main GOP rival, ended his campaign. Senate Minority Leader Mitch McConnell (R-Ky.), who ardently opposed the campaign finance reform law that McCain championed, endorsed McCain last Thursday. Gary Bauer, an evangelical leader, backed McCain last weekend.
