I really don't understand why a significant percentage of US Persons are still considering voting for President Obama in November. I'll explain below...
First, I am one of the dreaded "Independents", and have a Libertarian view (socially "liberal", fiscally "conservative") and I lean to minimal government. So in truth, the recent Democratic Party has left little interest for me.
That being said, why is Obama still competitive? I understand why Americans of "african" descent will overwhelmingly support Obama, and similarly why Mormans will overwhelmingly support Romney. That is simple human nature to support one's clan, and I have no issue with that. I also know hard core Dems and Repubs will vote the Party Line, even if Hitler were at the top of the ticket. I have issue with that, but accept it.
The question is, Why do roughly half of the 40-50% of the rest of us still support Obama? His Presidency, by any objective measure, has been a disaster. He has proven to have no leadership skills, no consensus building ability, and does not inspire confidence in many people. The nation is heading in the fiscal direction of Greece, and the personal liberty direction of Russia.
Romney is a centrist, not a right wing fanatic (Ryan is the right wing dude on ticket). Romney is a successful businessman and politician, and has a much better resume than Obama had in 2008. He is milquetoast, but has not had any major gaffes. He's had his issues with misstatements for sure, none terribly offensive.
I'm not terribly thrilled about Romney (would've preferred Ron Paul), but given the inability of Obama to actually perform adequately as President, the choice is obvious. I think Clint Eastwood was right, we need to replace those that don't work out.
