Three-fourths of Americans support increasing the minimum wage from the current $7.25 to $9 per hour, according to a new Gallup poll.

The poll shows 76 percent support the change -- up from 71 percent in March -- while 22 percent oppose it

The White House announced last week that President Obama supports a bill from Sen. Tom Harkin (D-Iowa) and Rep. George Miller (D-Calif.) that would increase the minimum wage, incrementally, to $10.10 per hour.

Obama had proposed a $9 minimum wage during his February State of the Union Address.

Polling regularly shows very high support for an increase in the minimum wage. The increase stands little chance of passage, though, as House Speaker John Boehner (R-Ohio) and even some Democrats have expressed opposition.

The new poll also finds 69 percent of Americans would support a minimum wage that is indexed to inflation.
