Democrat Hillary Clinton is trailing some potential Republican opponents in three key swing states, according to a new poll from Quinnipiac, and doing about as well against the GOP as one of her rivals for the Democratic nomination, Bernie Sanders.

The poll of likely voters in Colorado, Iowa, and Virginia—all states Barack Obama and George W. Bush won at least once—finds Clinton trailing Republicans Marco Rubio, Jeb Bush, and Scott Walker. In Colorado, Clinton is losing to Rubio by 8 points, Bush by 5 points, and Walker by 9 points; in Iowa, Clinton trails Rubio by 8 points, Bush by 6 points, and Walker by 8 points; and in Virginia, Clinton is behind Rubio by 2 points, Bush by 3 points, and Walker by 3 points.
