Ohio is Key for Romney's Victory

As we get closer and closer to the end of elections, there are less and less "battleground" states. This means that in order for Romney to win the election, he has to either win Ohio or win a number of smaller states, such as New Hampshire and Iowa. The problem with winning these smaller states  is that Obama has consistently held a lead over Romney in both states, making winning them unlikely. His best shot at this point is to try to win Ohio, which no Republican president has ever  won without. 

However, even in Ohio, Romney has a disadvantage. Firstly, Obama has over double the amount of headquarters in Ohio. Additionally the Obama campaign has reported a 19 to 52 point lead in the early voters in Ohio. This success in the election can be attributed to the ruling by Scotus not to ban early voting in Ohio, which allowed the elderly, miniorities, and poor ( who are likely to vote for Obama) vote before Election Day . Finally   Romney has consistently been polling lower than Obama in Ohio. A poll by PPP states that Obama is ahead by one point, and a poll by Gravis Marketing puts Obama and Romney at a tie. The fivethirtyeight blog has readjusted these polls to account for biases, and states that PPP and Gravis show Obama to lead by half a point and three points, respectively. Also, a previous poll by Rassmussen  states that Obama is leading by one point (although it was a telephone poll so that might skew results a little bit). '
Essentially, in order to win the elections, Romney must win Ohio, where Obama appears to have a slight lead.
