Mitt Romney is inevitable enough for Jeb Bush, reports ABC News. Bush today endorsed the GOP frontrunner after months of tongue-wagging over his silence—which included sitting on the sidelines while Romney won his own state's primary. The former president's brother, seen by some as a strong candidate himself in this election cycle, called Romney "a leader who understands the economy," and said that as "primary elections have been held in 34 states, now is the time for Republicans to unite behind Governor Romney and take our message of fiscal conservatism and job creation to all voters this fall."
