“Earlier today Gov. Romney was at it again. He’s been twisting my words around to suggest I don’t value small business,” Obama said of the presumptive GOP presidential nominee at a campaign fundraiser inside the Portland Convention Center, the second time in as many days he has hit back at the Republican attacks.

“In politics you have to endure certain amount of spin. Everybody does it; I understand it. Those are the games that are played in campaigns,” he said. “Although I have to say, when people omit entire sentences from a speech and they start splicing and dicing, they may have tipped a little bit over their skis.”

The president was referring to a new Romney TV ad and statements by the candidate and his surrogates that have taken out of context a line from one of Obama’s speeches.
