Next presidency thoughts

Today in class we touched on primaries for the presidency. That had me thinking a bit. Despite the fact that Obama has lived up to his expectations, who else can lead our country? I mean, there is no leader from the republican side and who else is going to run against Obama. I feel like he can be a great leader, but he needs time and cooperation. Because it's obvious no one else will step up to the plate. If our government doesn't play their cards right-after watching the news about the Arizona politicans- this country could be in for a rude awakening.
