Washington (CNN) - Sarah Palin's support for Republican Senate hopeful Joe Miller became a true family act on Friday, just days before the Alaska primary.
Palin, who endorsed Miller in June, posted another letter of support on her Facebook page Friday, and the former Alaska governor's husband Todd penned a fundraising letter that was mailed to Tea Party Express supporters.
Noting that he rarely sends fundraising letters, Todd said the effort is designed to raise $150,000 in the next 48 hours.
"A critical election for U.S. Senate is just 4 days away and constitutional conservatives across America need to rally together to support Conservative Republican Joe Miller for U.S. Senate in Alaska," Todd said. "Joe is up against the political establishment and special interests in Alaska, and I can tell you first hand that my own family has had to face such battles before."
In June, the Tea Party Express endorsed Miller in a bid to oust an incumbent Republican senator, Lisa Murkowski, who is part of the Senate GOP leadership.
The fundraising plea was echoed in Sarah Palin's Facebook page.
"Joe's campaign needs to raise about $30,000 for a crucial final media buy. We can do it if we all pull together."
The Alaska GOP primary takes place August 24.
