Tables turned: Mitt Romney and Paul Ryan have started attacking President Obama for cutting Medicare in order to pay for Obamacare, and Democrats now fear the attack “could cost us the election,” according to a new email.

“This could cost us the election,” Democratic Congressional Campaign Committee (DCCC) political director Kelly Ward wrote today. “The Romney campaign is up with a new ad campaign trying to confuse voters into thinking that Republicans are the ones trying to protect Medicare. You and I know that Romney and Paul Ryan are dead set on slashing seniors’ Medicare benefits to pay for more millionaire tax breaks — but we have to get the facts out to voters immediately.”
