Nationwide polls are useless in Presidential Elections.
It is encouraging, however, that Obama is ahead as we get closer to election day. This is basically the '96 election all over. Obama is good, not great. The Republican competitor is not Presidential Material. I'm sure around October, there will be a quip by Governor Romney that goes something like, "I've tried everything do you all have any ideas?"
That's not true.
At this point in our history..Romney is Presidential material.
Ronald Reagan and George W. Bush were Presidents..after all.
And Romney is a less compassionate and less charismatic President then George W. Bush.
So if elected look for a business oriented President less likely that Bush to win the hearts of foreign leaders and who doesn't care one whit about the middle class or poor.
