A new Washington Post-ABC News poll finds that while two weeks ago more battleground state voters had heard from President Obama's campaign than from Mitt Romney, now the Republican appears to have caught up. And on both sides, personal contact is highly correlated with voter preference: 

Nearly four in 10 voters, 37 percent, in the eight swing states — Colorado, Florida, Iowa, Nevada, New Hampshire, Ohio, Virginia and Wisconsin — say they have personally been asked for their support by a representative of the Obama campaign, either by phone, in-person or online in the past month. About as many, 35 percent, say they have heard from Romney’s side. Two weeks ago, more voters in this collection of states said they had recently heard from Obama than Romney.

Looking just at reported contacts in the past week, the campaigns are equally matched: 28 percent of all likely voters in swing states say they’ve heard from the Romney campaign, and 27 percent say so of Obama’s.

Campaign contacts are highly correlated with voter preferences. All told, about two-thirds of those who have been contacted by the Obama side support the president’s bid for reelection, and a similar proportion of those who have heard from Romney back his candidacy.
