Senator John McCain waited until just before the 2008 Republican convention to name his vice presidential pick, sticking to a timing tradition thought to pump up party activists before the big push to Election Day.
This year, there is at least a small chance that Republican Mitt Romney might break with tradition and name his vice presidential choice earlier in the summer, according to people advising the campaign.
Romney and a small circle of confidants are working quietly on a list of high-profile Republicans being considered for the No. 2 position. The confidants include his wife, Ann, long-time adviser Beth Myers and campaign manager Matt Rhoades.
Outside advisers to the Romney campaign, who spoke on condition of anonymity, say he has the option of announcing his choice well before the Republican convention where Romney will be nominated, in Tampa in late August.
