Romney also won a majority among the 49 percent of delegates who said they would opt for electability over ideology when choosing a presidential nominee. Romney won 64 percent of those voters, while Perry took 18 percent.
He did worse among those who said they wanted a presidential candidate with whom they were in complete ideological alignment. Among the 51 percent of voters who said they wanted someone with whom they agree, Romney won 38 percent. Perry took 16 percent, and former Godfather's Pizza executive and Rep. Ron Paul each took 13 percent.
Romney's support in Michigan is significant, but he doesn't appear to have a lot of room to grow. Only 19 percent of straw poll voters who did not vote for Romney said the former Massachusetts governor was their second choice. Perry received the most votes from Romney voters asked for a second choice, receiving more than a quarter of the vote.
The straw poll, conducted entirely by National Journal Hotline Friday and Saturday at the Mackinac Republican Leadership Conference, is not a scientific survey, but it does indicate how conservative activists see the presidential contest.
