Earlier, the Hatch campaign released results of another poll, conducted March 27-29, of 335 delegates, which said that Hatch had 62 percent of delegate support.
Between those two Hatch polls, the Strong Utah PAC a "super PAC" that supports Hatch released a poll saying the senator had only 50.5 percent support. That poll was conducted April 2-3.
Also, FreedomWorks a group opposing Hatch has said it has been polling, but would not release numbers. However, it said that it and ally groups have found polling numbers are varying over time, suggesting that support for candidates is "soft" and many delegates are still undecided.
However, Dave Hansen, Hatch's campaign manager, said the two polls by Hatch's campaign "show that the support for Senator Hatch is holding steady amongst the state delegates."
He added, "With only nine days until the state convention, we are feeling confident about where the senator stands." Hatch has taken four weeks off from work in Washington, D.C., to remain in Utah and campaign personally with state delegates.
If a candidate achieves 60 percent support of delegates at the April 21 state convention, he wins the party nomination and advances directly to the final election; otherwise the top two vote getters will face off in a June 26 primary election.
A total of 10 Republicans are in the Senate race, plus three Democrats.
