Mitt Romney acted every bit the presumptive nominee Friday, ignoring his fellow Republicans in favor of tearing into President Barack Obama.

This president has done it all wrong, Romney said at an Oklahoma City speech, according to the Associated Press. He's done the one thing that businesses can't deal with and entrepreneurs can't deal with - he's created more uncertainty.

The AP also reported that Romney praised Oklahomans for their consistently Republican voting record.

Romney also borrowed a favorite catchphrase of fellow candidate Michele Bachmann, claiming Obama would be a one-term president, according to the Oklahoman.
