Top donors increasingly believe Nikki Haley can topple Trump in the GOP presidential primaries and they're telling others to open up their checkbooks

• As Nikki Haley has risen in polls, so has her viability among top political donors, per The Times.
• Some donors are describing Haley's candidacy as one that's creating enthusiasm among party leaders.
• GOP donor Eric Levine told The Times that Trump's air of inevitability has "peeled away completely."

For months, former UN ambassador Nikki Haley has been stumping across the country in hopes of convincing GOP primary voters — and top donors — that her presidential bid is best positioned to put the party back in the White House.
