The Hill notes a number of Republican strategists say Romney's difficulties could be a drag on the rest of the ticket, including some key U.S. Senate races.
"If Romney doesn't improve, that could cost us our chance of picking up the Senate, for sure," said one senior strategist working on a number of Senate races. "Honestly, I don't know who's driving the train, but they need to get their message focused. "
The strategist said Romney's comments about the "47 percent" hurt the most in blue-leaning states like Connecticut and Massachusetts, as well as swing states where the GOP Senate candidates' hopes are closely tied to Romney's.
"The fortunes of these candidates are tied together in these closer states, in Ohio, Nevada, Virginia," he said. "There is a little give between Romney and our candidates, but that give is very small. "
