Goldschmidt has 1,962,386 votes to Gonzalez's 1,239,509, a lead of 722,877 votes.
Last week, Goldschmidt overtook Gonzalez for first place, but led by just 241,880.
The momentum appears to be with Goldschmidt, who just a few weeks ago was fifth in the voting but has steadily moved up.
Arizona fans have rallied behind Goldschmidt, staging voting parties, and during the broadcast of a recent D-backs game, fans were encouraged throughout to "Vote Goldy."
In addition, the team has set up computers at Chase Field where fans can stop by and vote.
D-backs manager Kirk Gibson, who generally downplays All-Star Game talk, has been vocal in his support of Goldschmidt.
"He's consistent through thick and thin," Gibson said. "He's great in his preparation and his [recovery]. When he gets in a game, he's really good at adjustments. He talks a lot and talks to his teammates a lot. When he goes up for an at-bat, regardless of what he does in his previous at-bat, he's got a game plan and he'll stick with it. He doesn't get too excited when things go good; matter of fact, he makes sure that he doesn't. When things go bad, he doesn't get down too much. He's just a very steady, consistent personality and attitude about it. He just believes that if he continues to be that way that things will work out for us."
Goldschmidt is the lone D-backs player to rank among the leaders at any position.
The D-backs have not had a position player start an All-Star Game since outfielder Luis Gonzalez did so in 2001.
