Two prominent Senate Republicans announced Tuesday they would seek a second term in the U.S. Senate, although their announcements had dramatically different implications on the 2016 presidential contest.
Ohio Sen. Rob Portman declared he would not seek the presidency, choosing instead to focus on his Senate re-election. The former White House budget chief and U.S. trade representative said he can play an important role as a member of the new Republican majority in the Senate, where he wants to help break the gridlock that has largely paralyzed Congress the past two years.
"I just see so much promise," Portman said during an appearance in Washington on Tuesday. "Getting the majority makes a huge difference. The Senate has been largely dysfunctional - unable to deal with even the most basic issues. And now we have a chance."
At the same time, Kentucky Sen. Rand Paul announced he would also seek a second term in the Senate, although his team says he could still run for president despite a state law that prohibits running for both offices at the same time.
"There are many options," Paul senior adviser Doug Stafford said when asked about the state law. "He hasn't decided on a presidential run yet. He will decide that in the next few months, but in either case he is running for Senate."
Two other GOP senators, Marco Rubio of Florida and Ted Cruz of Texas, are considering a presidential run but haven't announced decisions.
In an interview, Portman said he didn't think he could be as effective as a senator while at the same time running for president.
Paul does not necessarily agree. The Kentucky senator and libertarian favorite has been among the most aggressive potential presidential candidates in recent months, having already begun to hire staff in key states in addition to beefing up his policy credentials. He announced his re-election in a written statement on Tuesday issued from Washington, where he defended his foreign policy during a gathering with some of the nation's most powerful CEOs.
"I believe we've been everywhere all the time, we're about to bankrupt our country, and that there's great danger to what we're doing," Paul said and later added, "To those Republicans who love a Republican intervention, Iraq's worse off now. Do you think we're better or worse off with Hussein gone?" Iraqi dictator Saddam Hussein fell in 2003 after the U.S.-led invasion.
Given Congress' low approval ratings, senators face a tougher road to the White House than the crowd of Republican governors considering a 2016 bid. The last sitting senator to win the presidency before President Barack Obama was John F. Kennedy in 1960.
The Democratic National Committee ignored Portman's announcement, but lashed out at Paul.
"Whether he ultimately runs for Senate, president or both, Rand Paul is part of the problem in Washington," DNC spokesman Michael Czin said. "His record in the Senate is one of obstruction, self-interest and ideological crusading - not of working within the mainstream to get things done."
Portman, meanwhile, drew nationwide attention last year when he reversed his position on same-sex marriage. He said his support came after soul-searching on the issue after his son revealed he was gay.
Portman said his decision not to run didn't revolve around that issue, although some conservatives, including leaders of the National Organization for Marriage, had pledged to oppose his potential bid.
"It really wasn't a factor," he said in an interview. "Some people say it would have hurt me. Some people say it would have helped me. The country is obviously moving on that issue."
Portman said he sees a "broad field of impressive candidates" shaping up among the large number Republicans still considering a run. Portman, who served in the White Houses of both President Bushes, said he chatted Monday with former Florida Gov. Jeb Bush at a Washington fundraiser and that Bush indicated he hasn't decided yet on 2016.
Bush on Monday night said he would make up his mind "in short order."
Portman, a 58-year-old Cincinnati native, could also resurface in 2016 presidential campaign as a potential running mate to the GOP's eventual nominee. He was vetted by Mitt Romney's 2012 presidential campaign and serves a swing state that's been crucial for Republicans.
But Portman said that's not where he's headed.
"I have been through it," Portman said. "It's obviously not something that you run for. But I'm not interested. I'm interested in staying in the Senate."
