The Garland Tucker campaign has released internal polling showing that Thom Tillis is undergoing a “spectacular” collapse in support among Republican voters:

You see it once every thirty or forty years in politics: An incumbent Senator collapsing in his own primary.

Garland Tucker announced in May. Months earlier he had taken a poll and, after airing TV ads in May, June and July, he polled again. The poll, a random sample of 500 people who vote in the Republican Primaries, was done by Diversified Research which was founded by the late Arthur Finklestein who polled for North Carolina Senators Jesse Helms, John East and Lauch Faircloth.

The ballot question tells the story of what happened to Thom Tillis.

Ballot: In the campaign’s first poll, taken before Thom Tillis flip-flopped on President Trump’s Border Emergency Declaration and when Garland Tucker was unknown, Tillis led then by 56 points. In the July poll Tillis’ world turned upside down:

1st Poll July Poll +/- Garland Tucker 7 30 +23 Thom Tillis 63 40 -23 Undecided 30 30 0

Tillis plummeted by 46 plus points, ending up with only 40% of the Republican Primary voters supporting him – a thin number for an incumbent Senator.

Worse for Tillis, he now only leads Garland Tucker by 10 points with 30% of the voters Undecided. There’s a long history that shows, in a campaign between an incumbent like Tillis and lesser-known challenger, Undecided voters usually break against the incumbent by 2 to 1.
