The Democratic National Committee has unleashed relentless attacks on a handful of GOP candidates in the ever-widening 2016 presidential field, while virtually ignoring others.

The Hill tallied the DNC's social media mentions of Republican presidential contenders, scanning press releases, tweets and Facebook posts from July 2014 through June 2015, to see whom the group has been hitting the most over the past year.

Paul ranks as the DNC's top target, with 203 mentions. Christie follows with 202 attacks, and Bush trails closely behind him with 199.

With a slew of declared candidates and even more potential contenders, the DNC has spread its fire wide. The DNC has hit 17 potential Republican contenders over the last year.

That's a marked contrast from the 2012 cycle, when most attacks were aimed at Mitt Romney, who was seen as the likely GOP nominee early on.

The large number of GOP candidates could pose a challenge for the DNC over where to direct their fire.

“The profusion of candidates and any drama their competition generates may suck attention away from Democrats as they attempt to define the 2016 election and recruit donors and volunteers,” said Michael Cornfield, research direct for Global Center for Political Engagement.

While Paul, Christie and Bush have drawn the most attention overall from the DNC, the group's targets have changed as Republican contenders enter the race and slide up and down in the polls. That's forced the DNC to keep their focus on a broad field.

“The DNC mentions GOP candidates whenever it sees a chance to highlight a difference between the two parties,” Cornfield added. “As manifest in something a leading GOP candidate said or something that just broke in the news.”

In July 2014, well before any declared candidates, Christie received the most GOP mentions with 10, but Paul garnered seven attacks and Walker six, reflecting their high standing in early GOP polls.

Christie, Paul and Walker dominated the DNC's targets the last six months of 2014, but with no emerging Republican frontrunner, Democrats hit a total of 18 potential contenders.

New candidates quickly drew the DNC's attention. Cruz took the top spot in March, when he became the first official major presidential contender, with 29 mentions. Cruz quickly vaulted to the top of the polls that month, but Walker, Paul, Bush and Rubio also saw their DNC mentions in the double digits.

But one candidate is garnering more and more of the DNC's attention. In the second half of 2014, the DNC hit Jeb Bush only 13 times, but in 2015 his mentions have surged.

The DNC has ramped up social media attacks on Bush each month this year. He received 19 hits in March, 35 in April, 46 in May and 57 in June.

Surprisingly in June, though, Paul still took the top spot, with the DNC knocking him a whopping 71 times.

GOP campaigns are taking those hits in stride, touting the attention as a sign they are viable threats.

“It should come as no surprise that the DNC is targeting Senator Rand Paul with their attacks — he is the single biggest threat to Hillary ClintonHillary Diane Rodham ClintonNevada Senate passes bill that would give Electoral College votes to winner of national popular vote 2020 Dems break political taboos by endorsing litmus tests Iowa Democrats brace for caucus turnout surge MORE’s candidacy,” said Sergio Gor, communications director for Paul’s campaign.

The DNC, though, isn't letting up on the Republican presidential field.

“Let’s talk about some other numbers voters might be even more interested in," Holly Shulman, the DNC’s national press secretary, told The Hill.

"Nine is the number of credit downgrades in Chris Christie’s New Jersey. 48 percent is how much tuition climbed in Bush’s Florida. $2.2 billion is the budget deficit in Walker’s Wisconsin. Too many to count is the number of positions Rand Paul has taken on any given issue," she continued.

"And 100 percent of the Republican candidates want to repeal the Affordable Care Act that has helped 16 million Americans gain access to health insurance.”
