Romney himself performed well. The campaign sat all summer without responding to attacks, and then basically sat out September. Only after the first debate did it even look like they were trying to win. The second debate was good, too, but by the third debate they were had backed off and sat back as if in the lead. Romney did perform on stage better than expected, but their campaign message and strategy failed terribly.
Guy did make an awful lot of visits though, but mostly to raise funds from small groups of donors.
In the end he exhibited entirely too much derrier and not enough interest. That's always fatal, politically speaking, in this state where Republicans are a hopeless minority although we have neat ideas and now control all the major offices of state government and the state legislature.
