Race for the White House tightens

Less than a week before the Republican convention begins, the race for the White House is a virtual tie.  According to a Fox News poll of likely voters, the Mitt Romney-Paul Ryan ticket receives the backing of 45 percent, while the Barack Obama-Joe Biden ticket garners 44 percent.  
The poll, released Thursday, is the first Fox has conducted among likely voters this year, which means an apples-to-apples comparison can’t be made to previous polls.  Likely voters are eligible/registered voters who will most likely cast a ballot in this year’s presidential election.
This is also the first Fox poll to ask about the top and bottom of the major party tickets:  Democrats Obama and Vice President Joe Biden against Republicans Romney and Paul Ryan.  Romney announced his vice presidential pick of Wisconsin Rep. Ryan on August 11.
