Vice presidential nominee Indiana Gov. Mike Pence has reportedly taken it upon himself to make nice with anti-Donald Trump forces on the right, including Sen. Ted Cruz of Texas and Ohio Gov. John Kasich.

Pence's efforts to win over doubtful Republicans comes even after the GOP nominee has vowed to thwart their re-election efforts.

Still, despite Trump's threats in public, Pence appears committed to the role of peacemaker, according to the Wall Street Journal.

To that end, the Indiana governor has reportedly met with former GOP presidential candidate and Florida Gov. Jeb Bush, as well as with Arizona Sens. John McCain and Jeff Flake.

Pence is even reaching out to those in right-leaning commentary who have not yet jumped on the Trump train.

"His pitch is subdued and often aimed at reminding his fellow Republicans about what unites them, including old friendships and alliances," the Wall Street Journal reported.

What's interesting about Pence's new role is that it flips the script, as it's normally the running mate who serves as an attack dog, while the presidential candidate works to build alliances.

"Mending fences isn't usually part of a vice-presidential nominee's job," Mike Steel, a former aide to House Speaker Paul Ryan, told the Wall Street Journal. "But we've never before seen a nominee like Donald Trump, who has alienated huge swaths of the party."

Pence was not told by Trump to go out and win over doubtful Republicans, and reportedly took on the role all by himself.

"Mike has longstanding relationships with many of these people, and part of his role is to unify the party," Pence's spokesman said.

Has Pence been successful? The best anyone can say right now is that he has been met with mixed results.

He spoke with Cruz last week, but it's uncertain if there has been any change in the Texas senator's position on Trump. Pence has also been unable to connect with Kasich.

As for his recent meeting with Jeb Bush, who has vowed not to vote for the GOP nominee, neither Republican will comment on the details of their talk.

Pence's meeting with Flake, who is vocally anti-Trump, does not appear to have been successful.

"He talked about the ticket. I certainly respect him," the Arizona senator told CBS News, describing Pence's sales pitch as being, "Donald Trump is a different guy in private than he has shown in public.

"He made a good case," Flake added.

Still, the senator has hasn't budged on his anti-Trump position.

Pence has yet to connect with other notable anti-Trump GOP lawmakers, including Sen. Ben Sasse of Nebraska and Kelly Ayotte of New Hampshire.

A spokesperson for the Republican presidential team did not respond to the Washington Examiner's request for comment.
