GRAND JUNCTION, Colorado - US Republican presidential candidate Mitt Romney acknowledged on Tuesday he is considering naming his choice to serve as vice presidential running mate earlier than usual to better compete with President Barack Obama.

As they work from a short list of leading Republicans, Romney and his advisers say they are weighing whether he should announce his choice some weeks earlier than the traditional time of around the Republican National Convention, which is to be held in Tampa in late August.

The reasoning, advisers say, is that two candidates would be able to raise more money and engage Obama and Vice President Joe Biden in battle with polls showing Americans closely divided on whether to pick the Republican challenger or Democratic incumbent in the November 6 election.
