Global investors, skeptical about President Barack Obama’s ability to turn around the economy, nonetheless aren’t enamored with the Republican alternatives.

While a plurality of investors said Obama’s re-election would be a bad thing for U.S. markets, 57 percent said in a Bloomberg Global Poll that the current contenders for the Republican presidential nomination aren’t offering good ideas to lessen U.S. economic woes.

Globally, Obama ran slightly ahead of Republican Mitt Romney in a hypothetical matchup, 39 percent to 35 percent, when investors were asked whose presidency would be better for the world economy. That’s a reversal from the last poll, in September, in which Romney led Obama, 37 percent to 34 percent.

In the latest poll, Obama beats Republican Newt Gingrich more decisively on the global economy question, 45 percent to 29 percent.
