Super Tuesday!

Mitt Romney wins Ohio and is the clear winner of the day however the other candidates have committed to fighting until the end. Really? Seriously? I can understand Rick Santorum staying in the race but can anyone explain to me why Newt Gingrich, even if he did win Georgia and hopes to win more southern states, is staying in the race? not to mention Ron Paul? Do we really have to wait until the convention in August for a winner to be declared?
Some have said this is good for the President and the democratic party since the republican primaries have been a bit ugly and millions of dollars have been spent on negative ads that are leaving a bad taste in the mouth of most voters. Others have said that this fight will make the ultimate winner stronger and better able to take on the president in the fall. Also, having several candidates remaining in the race raises various issues and generates useful debates. Could it also be a ploy by the candidates to gain cabinet positions or a selection for vice president if one of them is elected? That seemed to work well for Hilary Clinton.
After all of this fighting will the candidates be able to come together and support the eventual nominee?
I am not quite sure where I stand on this but I do I think August to November is too short a period to have the republican nominee and the president debate and campaign against each other.
However it goes, I do hope the extreme partisan politics that currently exists improves over the next 4 years. I truly hope there can be some middle ground on the issues and get bills, laws and doctrines passed that can benefit this country as a whole.
Thoughts?
P.S. Sarah Palin w her hubby on CNN casting her vote in Alaska wearing a NRA shirt. Visions of the SNL weekend update skit comes to mind. Hilarious!
