No immediate boost for Romney after Ryan selection

Republican Mitt Romney received no immediate boost to his White House bid by naming US Representative Paul Ryan as vice-presidential running mate, according to a Reuters/Ipsos poll.

Some 51% of those surveyed said the decision did not change their opinion of Romney, a former private-equity executive and Massachusetts governor who will face President Barack Obama in the Nov 6 election.

Another 26% in the online poll said they viewed Romney more favourably after he added the 42-year-old Wisconsin congressman to the ticket on Saturday, while 23% said they viewed him less favourably.
