Barack Obama takes his final campaign plea to the airways. Tonight, Obama will go on national TV with a 30-minute infomercial about himself and his campaign. Even with the math beginning to add up on his side, many political strategists wonder if Obama’s infomercial could backfire on him.

And just a day before Obama’s video, CNN’s Campbell Brown reminds the American public that Obama reneged on his campaign finance promise. Obama’s decision to not take public financing allowed him to raise more than $600 million dollars (more than Bush & Kerry raised in 2004) so far, and buy 30 minutes of airtime for his infomercial on five different networks.

Although the presidential race has not been decided, a group of conservatives are discussing the political impact of Gov. Sarah Palin. If McCain and Palin win, she puts social conservatism in the White House. If the Republican ticket loses, she will be a potential presidential candidate in 2012 and leader of the social conservative movement. Is Palin the future of the Republican Party?

Palin has called for a “clean break” from the Bush Administration’s energy policies, which she says are too dependent on foreign oil.

And the U.S. stock market was slightly higher Wednesday after “one of the biggest single-session gains in history” on Tuesday.
