Nearly half of American voters think the IRS targeted conservative groups at the request of the White House, and most want Congress to keep investigating the matter.

The latest Fox News poll also finds 69 percent don’t feel President Obama has followed through on his vow to “find out exactly what happened on this.”

By a 49-41 percent margin, voters believe the Obama administration “intentionally had the IRS target conservative political groups.” That includes 26 percent of Democrats, 52 percent of independents and 71 percent of Republicans.

Meanwhile, 67 percent of voters want Congress to keep investigating the IRS until “someone is held accountable.” An all-time high of 78 percent thought lawmakers should investigate the IRS in early June.

The poll shows agreement across party lines: Majorities of Republicans (77 percent), independents (67 percent) and Democrats (57 percent) favor Congress continuing to investigate until “someone is held accountable.”

Most of the tax-exempt groups targeted by the IRS have “tea party” in their name. Among voters who consider themselves part of that movement, 80 percent think the White House intentionally had those groups targeted, and 87 percent say the IRS investigation should continue.

Overall, 72 percent of voters disagree with the president when he says there is not even a “smidgen” of corruption regarding the IRS targeting conservative groups.

The Fox News poll is based on landline and cell phone interviews with 1,012 randomly chosen registered voters nationwide and was conducted under the joint direction of Anderson Robbins Research (D) and Shaw & Company Research (R) from April 13-15, 2014. The full poll has a margin of sampling error of plus or minus three percentage points.
