The Donald Trump vice-presidential guessing game is over, according to widespread reports, and the winner is Indiana Governor Mike Pence.

Roll Call first broke the story citing an anonymous source, The Indianapolis Star then reported that Pence has dropped his re-election campaign in order to be on the state’s ballot as Vice President, The New York Times joined those confirming Pence was the likely pick, and now ABC News is reporting the governor has flown to New York City for what was expected to be Friday’s official announcement.

A radio host before becoming a politician, Pence is a former Congressman who served six terms in the House of Representatives. Known for his conservative principles, he opposed several of President George W. Bush’s key initiatives, including No Child Left Behind, Medicare Part D and the Troubled Asset Relief Program bank bailout. He eventually rose to become the fourth-ranking Republican in the House before running for governor in 2012.

As governor, Pence has faced criticisms from both sides of the political aisle. The left has targeted him for signing multiple pro-life bills, including one that makes choosing abortion because of a baby’s sex or race illegal. He signed a Religious Freedom Restoration Act law in Spring 2015 that drew a tremendous backlash from LGBT activists and corporations, leading him to sign a modified version shortly thereafter.

The latter move left conservatives infuriated with a candidate many wanted to run for president in 2008 and 2012. Pence has also been criticized for expanding Medicaid in a compromise with the Obama administration that implemented conservative priorities like health savings accounts. He pulled Indiana out of Common Core, but instituted education policies that have garnered significant conservative criticism.

On budgets and taxes, Pence was one of four governors who received an “A” from the Cato Institute in its 2014 rankings.

“Mike Pence of Indiana has been a champion tax cutter, and he has held the line on spending. He signed into law a 2013 tax package that cut the individual income tax rate from 3.4 to 3.23 percent and repealed the state’s inheritance tax,” according to Cato’s report. “In 2014 he approved cuts to the corporate income tax rate and to business property taxes, both of which will be phased in over time.”

Pence’s conservative pedigree was rarely challenged during his 12 years in the House, where he took the Republican Study Committee from a little-noticed group of House conservatives to being a powerhouse organization that regularly pushed the GOP to the right on policy. In 2006, he tried to broker a deal between Bush and conservatives on immigration, an effort that was praised by many in Republican circles, but decried by hard-liners like former Rep. Tom Tancredo.

A Trump/Pence ticket will balance the hard-charging charisma of Trump with the balanced, policy-centric Pence. It will also settle many conservative concerns about Trump’s seriousness about issues like abortion, and likely add significant fundraising power to the Trump campaign.

Reactions to the likely pick included praise from House Speaker Paul Ryan (R-WI) and House Majority Leader Kevin McCarthy (R-CA). SBA List president Marjorie Dannenfelser also expressed admiration for Pence as Vice President, saying in a statement, “Mr. Trump’s selection of Gov. Mike Pence is an affirmation of the pro-life commitments he’s made and will rally the pro-life grassroots.” Huffington Post reports that other Republicans are offering similar words of affirmation.

Erick Erickson, however, was less pleased. The former Red State Editor-in-Chief criticized Pence on Twitter for retreating on religious liberty, and offered other critical commentary in blog posts.

From the left, MoveOn.org Political Action Executive Director Ilya Sheyman said that picking Pence would show that Trump is “doubling down on his divisive and hate-filled approach to politics.” Sheyman specifically highlighted Pence’s socially conservative principles, and concerns Pence had about Syrian refugees settling in Indiana.

One word of warning: Although all signs to Pence, multiple people on the Trump campaign have denied that a final pick has been made, and The New York Times cautions “the party’s mercurial presidential candidate may still backtrack on his apparent choice.”

Donald Trump was planning to formally announce his VP pick at 11 a.m. Eastern on Friday. However, in the wake of Thursday evening’s terrorist attack in Nice, France, Trump announced that he is postponing his scheduled press conference.

In light of the horrible attack in Nice, France, I have postponed tomorrow's news conference concerning my Vice Presidential announcement.
