Former Alaska Republican Gov. Sarah Palins political action committee, Sarah PAC, raised almost $1.6 million in the first six months of this year, it will report in Federal Election Commission filings.

Sarah PAC had slightly more than $1.4 million in the bank at the end of June, after having spent about $1.6 million — about as much as it raised — from January to June.

The first half of this year saw a revamped political operation for Palin. The former vice presidential candidate relaunched Sarah PACs website this spring and embarked on a national bus tour sponsored by the PAC. That tour, along with some of Palin's moves in primary states, has stoked speculation that she might run for president.

The money raised by Sarah PAC cant be put toward a presidential run, but the haul reflects the extent of Palins latent support, which could be converted into support for a White House bid.

We at Sarah PAC are very pleased and grateful for the tremendous support that Governor Palin receives from everywhere across our country, said Tim Crawford, the PACs treasurer. Sarah PAC more than doubled the amount we raised as compared to the same time period in 2009. We received more that 36,700 contributions from over 24,000 contributors.

Donations averaged less than $50 per person.

Among the PACs expenditures were $65,000 in contributions to candidates and an $18,700 donation to the Young Americas Foundation, an organization for young conservatives.

Most of Palin's political contributions came at the end of June, one day before the semi-annual filing deadline.

Thirteen Republican incumbents or candidates received $5,000 each from Palin's PAC.
