Sanders, on the other hand, would beat all GOP candidates, the poll shows. He has a 17-point lead over Trump, a 12-point lead over Cruz and a five-point lead over Kasich.

Sanders hit on his recent poll numbers Thursday night in the Democratic debate, citing his victories in eight of the last nine contests.

“When we began this campaign almost a year ago, we started off at 3 percent in the polls,” Sanders said. “We were about 70 points behind Secretary Clinton. In the last couple of weeks, there were two polls out there that had us ahead.”

Women and younger voters continue to favor the Democratic candidates, the poll shows, with Trump performing the worst among both groups.

Both front-runners are viewed unfavorably among registered voters overall, the polls show. Sixty-three percent of voters viewed Trump unfavorably, a six-point increase from the same poll last month. More than half of registered voters view Clinton unfavorably, similar to results from a month ago.

The poll was conducted by telephone April 8–12 among 1,320 adults and 1,098 registered voters with a margin of error of 3 points.

The CBS survey falls in line with a Fox News poll also released Thursday that showed Kasich beating Clinton in a general election, while Clinton beats Cruz and Trump. In that poll, Sanders also beats all GOP candidates.
