Speaker Paul Ryan would not fare well against either Democratic presidential candidate in the general election if he were to become the Republican nominee, according to a new poll.

{mosads}The Rasmussen survey released Thursday found that the Wisconsin Republican trails Democratic front-runner Hillary Clinton in a hypothetical match-up, 40 to 34 percent. The results are similar against Bernie Sanders, who would beat the Speaker, 41 to 34 percent.

In both matchups, at least a fifth of voters say they’d prefer another candidate.

The poll comes amid rumors that the GOP leaders are hoping to nominate Ryan during a contested convention as a last-ditch effort to block the party’s front-runner, Donald Trump. Ryan has said that he’s not interested in the nomination.

The poll found that 59 percent of Republican voters view the Speaker favorably, while 64 percent of Democrats view him unfavorably.

His unfavorable numbers are slightly higher than his favorable ratings among all voters, 44 to 39 percent. 

The poll of 1,000 likely voters has a margin of error of 3 points.
