Rick Perry, right."](CNN) - Texas Gov. Rick Perry has been in office for 10 years in a heavily Republican state, but his Democratic challenger raked in more campaign cash during the most recent fundraising period.
Former Houston Mayor Bill White collected nearly $7.5 million between Feb. 20 and the end of June, while Perry took in $7 million.
But more impressive for White is the substantial war chest he has amassed since launching his bid last December.
With the election less than four months away, White has more than $9 million left in the bank.
Perry, who had to slog through a months-long primary fight against Sen. Kay Bailey Hutchison and conservative activist Debra Medina, has $5.8 million cash-on-hand.
White's campaign is touting support from small donors and first time contributors. More than 11,700 new donors gave to the campaign during the most recent filing period, and 75 percent of White's donors have $100 or less, according to the campaign
Perry's campaign said 87 percent of its contributions were less than $500.
