More than half of Republican voters doubt that Louisiana Gov. Bobby Jindal will be the GOP’s nominee for president next year, according to a national poll conducted by Rasmussen Reports in the days since Jindal formally launched his presidential campaign.

The poll found just 28 percent believe Jindal has a shot at besting the crowded Republican field and seizing the nomination, to the 52 percent who say he’s unlikely that he’ll be their nominee.

According to crosstabs Rasmussen provided to The Advocate, likely voters were pretty evenly split between finding Jindal favorable (30%) or unfavorable (32%), but 38 percent didn’t know enough about Jindal to say either way.

Jindal, who is in Iowa Friday, is plotting a campaign that will attempt to woo conservative Christians and heavily focus on efforts in Iowa — the first state to caucus in the primary.

The Rasmussen survey included 1,000 likely voters and the margin of error is 3 percent, with a 95 percent level of confidence.
