Thompson is running two of his his ads in Iowa and one in South Carolina.
COLUMBIA, South Carolina (CNN) - In a fundraising e-mail blast sent out Monday morning, Fred Thompson's presidential campaign asked supporters for help in getting more TV ads on the air in two key early states.
Thompson's ad "No Amnesty" is on the air in Iowa and "Consistent Conservative" is running in both Iowa and South Carolina. Thompson says in the e-mail: "To build even more momentum though, I'm going to need the resources to further get my message out."
The email says Thompson needs more money to stay on TV in Iowa and South Carolina, two states with conservative voting blocs crucial to Thompson's bid.
However, Thompson's e-mail pitch is more straightforward than most: he asks supporters to cover the cost of an entire 30-second ad, and outlines just how much the campaign says those ads will cost in different media markets.
"You can pay for a 30-second ad for my campaign in Sioux City, Iowa simply by contributing $70 to my campaign, and $250 will buy an ad in Greenville, South Carolina," the e-mail reads.
"If you and your friends and family can combine to give $850 to my campaign, I can buy a prime-time advertisement in Charleston, South Carolina."
The e-mail makes no mention of New Hampshire, where Thompson is not running ads and has struggled to gain traction in the polls. On ABC this weekend, Thompson acknowledged, "I don't know what the situation is going to be in New Hampshire. I haven't done as well there."
