Rasmussen Reports:

Democrats are still trusted more than Republicans to handle the economy by a 44% to 39% margin, but their advantage on the issue has been slipping steadily since November.
The latest Rasmussen Reports national telephone survey of likely voters found 17% are not sure which party they trust more to handle the economy, showing no change since the last poll conducted a month ago.
In the first poll conducted after Barack Obama was elected president, the Democrats held a 15-point lead over the GOP on economic issues. In December, their lead dropped to 12 points. In January, prior to Obama’s inauguration, Democrats held a nine-point lead on the issue.
