As Election Day approaches and the number of voters who are undecided shrinks, President Barack Obama is increasing his lead over challenger Mitt Romney in certain key voter polls. However, the overall race is too close to make a call.

The past week has been tough for President Obama and his challenger. With the protests in the Middle East and North Africa and the deaths of U.S. diplomats in Libya, Obama has had to deal with more than just his reelection campaign. Romney on the other hand had to fend of dissension from fellow Republicans along with Democrats for his remarks about the attack that took place in Libya on the consulate, which seemed only to be to gain a foothold politically, when national unity was more important.

In this case, Obama has much more to do than Romney, both for what transpired in Libya and how he has to respond. This could help define his reelection bid.

With only 50 days remaining before the election, the White House should be excited, at least recent polls say so. The post convention boost Obama received has endured and most significantly in battleground states that are so important to Obama’s reelection.

According to the latest Wall Street Journal/NBC poll, Obama is leading his challenger by 7 percentage points in the state of Ohio and by 5 percentage points in both Virginia and Florida. A poll by the Philadelphia Inquirer has Obama in front of Romney in the Keystone State by 11%.

The poll said that Democrats in Pennsylvania have consolidated more behind Obama than other states with over 77% in favor of Obama and just 13% behind Romney. In Pennsylvania, Obama’s favorable rating jumped 3 points following the convention, while is unfavorable rating fell by 6 points. Following both conventions, the favorability of Romney increased slightly, but his personal popularity went down.
