The number of Americans pointed to the economy as the important issue of the campaign year has soared from 46 percent last November to 67 percent, according to an AP-Yahoo poll conducted April 2-14.

The poll says about two-thirds of those making under $100,000 attach “extreme importance” to the economy as do nearly 6 in 10 earning more. However, none of the remaining presidential contenders can claim a lion’s share of those voters, although those who say they are extremely concerned about the economy lean towards the two Democrats. Both groups divide evenly between McCain and each Democrat in head-to-head match-ups. Democrats divide between Hillary Clinton and Barack Obama about the same whether or not they name the economic situation as extremely important to them.

AP Yahoo concludes: “The economy is the top problem, but so far it’s not driving votes.”
